Is your dog bowl safe?

There are a wide variety of dog bowls on the market - plastic ones, slow down eating ones, silicon ones, stainless steel ones, ceramic ones, stoneware ones, and yes, even paper ones and ones made of sugar cane.

But how do you know if your dog bowl is safe?

We've done a bit of research on the different types of dog food bowls on the market...here's what we found:

Plastic

Some of the most popular dog bowls on the market are plastic. But unknown to many, they can be the most dangerous bowls with which to feed and water your pet! There are a couple of reasons for this:

One reason is that plastics scratch and those little crevices can harbor unhealthy bacteria, that even a good safe cleaning can't deter.

In addition, there are many reports in the news that plastics can emit chemicals like Bisphenal A, or BPA. Every few years, articles regarding the safety of plastics hit the news headlines – most recently in the form of reports of a chemical found in baby and sports bottles: Bisphenal A, or BPA.

What is BPA? The EWG says, "bisphenol a (BPA), a synthetic estrogen used to harden polycarbonate plastics and epoxy resin, is the focus of a growing number of research studies and legislative actions, reflecting mounting scientific evidence that it causes serious and sometimes irreversible damage to health, even at the low doses to which people are routinely exposed."

The Environmental Working Group also goes on to say..."in laboratory tests, trace BPA exposure has been shown to disrupt the endocrine system and trigger a wide variety of disorders, including chromosomal and reproductive system abnormalities, impaired brain and neurological functions, cancer, cardiovascular system damage, adult-onset diabetes, early puberty, obesity and resistance to chemotherapy." So if they are having this kind of effect on humans, imagine what they are doing to our little dog bodies!

Plastics can also emit dangerous Phthalates, according to the EWG. "These chemicals, called “plasticizers,” are a group of industrial chemicals used to make plastics like polyvinyl chloride (PVC) more flexible or resilient and also as solvents. Phthalates are nearly ubiquitous in modern society, found in, among other things, toys, food packaging, hoses, raincoats, shower curtains, vinyl flooring, wall coverings, lubricants, adhesives, detergents, nail polish, hair spray and shampoo."

In addition, HealthyStuff.org, an organization who tests many pet products for levels of lead, chlorine, arsenic and more, indicates that even though some plastic pet bowls may be BPA free and certified as FDA food safe, some may contain medium levels of lead.

And these chemicals can leach from plastic containers into your dog's food, potentially exposing them to dangerous chemicals with harmful side affects.

There are some safe food plastics, and generally speaking most human plastics containers can be identified by their recycling codes that can help you find the safe ones. But the pet industry is slow to add this helpful id tool to pet products, so we are left not knowing what plastic pet dish is safe and which is not, or taking the word of the manufacturer.

Yes, there are some safe plastic bowls, but how do you know for sure, without having them tested in a trusted lab?

Stoneware

According to HealthyStuff.org some stoneware pet bowls may contain medium levels of dangerous lead that could be harmful to your dog.

In 1973, the U.S. Environmental Protection Agency began phasing out leaded gasoline, a process that was to drag on until 1996. Lead was banned in household paint in 1978. As a result, according to the National Institute of Environmental Health Sciences, lead levels in the blood of American children have dropped by 86 percent since the late 1970s."

The EWG says..."the insidious symptoms of slow lead poisoning -- impaired intellect, memory loss, mood swings, infertility, nerve, joint and muscle disorders, cardiovascular, skeletal, kidney and renal problems and possibly cancer -- were not fully recognized until the late 20th century.

Some manufacturers tout their stoneware bowls as lead free. But, while HealthStuff.org is sharing a lot of research about stoneware pet bowls, they have yet to test every bowl on the market.  So why potentially expose your dog to such a dangerous chemical?

Silicone

Lately we've been seeing several silicone based pet food bowls hit the market. While they are deemed made of FDA approved food based silicone, we are with the the 'jury is still out,' pack on this new method of feeding.

According to Wikipedia, silicones are largely-inert, man-made compounds with a wide variety of forms and uses. Typically heat-resistant, nonstick, and rubber-like, they are commonly used in cookware, medical applications, sealants, adhesives, lubricants, insulation, and breast implants.

Over the years, we've read about the problems women have had with silicone breast implants, (the same stuff used to create food safe silicone bowls). So many dangers have been found with the various methods we use for feeding, that I'm of the 'better safe than sorry" set. Time will tell...

Ceramic

Many ceramic dog bowls can be a good choice if you do your homework and select carefully. Some glazes used to coat the dog bowl could contain lead and other chemicals.

So if you decide to use a ceramic bowl make certain it is intended for food use and that it is coated with a lead free glaze. And also be certain to check the bowl often for little cracks in the glaze, that can not only harbor bacteria, but can also potentially be ingested if cracked or chipped.

Sugar Cane and Corn

Many disposable pet bowls made of sugar cane and corn are hitting the market. Patterned after human disposable paper plates and made from sugar cane or corn, these pet bowls are touted as being very eco-friendly and green, as well as safe for dogs. Many say after several uses, you can put them into your compost pile to biodegrade, which would cut down on added waste to landfills, and the inability to actually biodegrade when buried under all that trash at the landfill.

Since sugar cane and corn in very low ingestion levels is not toxic or dangerous for dogs, we feel these dishes would be a nice emergency or travel option for dogs. We would keep a watchful eye on my sis, Gracie, however, since she would perhaps be apt to eat something like a bowl made of sugar cane...she's like that you know :) And we know that anything like this in large proportions wouldn't be good for her intestinal tract.

Stainless Steel

Over many years, stainless steel has be proven to be the safest material for making and storing foods. It is durable, sanitary, rust-free, and non-leaching. And the best part is that they can last a lifetime, and save you money! In their tips to avoid certain chemical exposure, the EWG recommends in many instances to replace non-safe plastics with stainless steel.

What we use!

So what's a dog to do? We recommend going stainless steel. It is widely believed to be one of the safest dog food and water dispensing bowls. It's what we use for all our meals and water, whether at home or on the road, for us pups and our kittie bros.

You can purchase many sizes and types of stainless steel dog bowls, including slow down eating and non-skid, small or gigantic!

Properly cared for stainless steel pet bowls won't harbor dangerous bacteria, and they don't emit dangerous chemicals.

Be sure to clean your stainless steel bowl after every use to ward off potential illness from bacteria, and don't clean it with any abrasive material like steel wool. Just use a safe eco-friendly dish soap and hot water, or better yet, do what we do, clean with a nice mixture of vinegar and water.

Update: Please be sure to inquire at your pet store if your stainless steel pet bowls are radioactive and lead free, as reports have been made that some stainless steel pet bowls may contain low levels of lead and radiation. See more information below to learn more.

Oh, and watch what you store your pets food in as well! There are many, many pet storage containers made of plastic, but we are happy to see stainless steel and jute pet food storage containers hitting the market as well.  Watch for resource links in our next post.

Happy Eating!

Update: 7-1-2012 - On July 30th, 2012, stainless steel pet bowls sold in several Petco stores in the Chicago area were found to be radioactive and taken off the shelves. Read our updated post to learn more about these bowls, how they may have become radioactive and how you may be able to purchase stainless steel bowls that are safer.

  1. Very informative blog. I like the stainless steel bowl idea. I get tired of replacing the 'chewable' dog dishes.
    "Doc" won't like his new bowl. Ha, Ha, too bad--but I will.
    Thanks for the info.

  2. I use stainless steel. Organic dog food shouldn't be served in toxic plastic. :)

    ReplyDelete
  3. Definitely, only stainless! Would never use anything else.

  4. I have a question.

    We slightly heat our dogs food in the microwave (since it's kept in the fridge) and can't use stainless steel. I hate microwaving any plastic. Can anyone recommend a ceramic or crockery bowl brand or line that would be safe?

  5. Hi Deanna - Leslie and Johann here from Raise a Green Dog.

    While we completely understand the convenience factor of microwave ovens, we have read a lot of research that outlines that microwaving food can actually destroy the valuable nutrients in foods.

    Our recommendation would be to quickly and slightly heat your dogs food on the stove, just to room temperature, so that it can more easily be digested. And it will provide all the standing nutrients that the food original intended.

    Happy eating!

  9. Very informative article! It is shocking how harmful a plastic bowl can be. Time to get a stainless steel one. Thanks for the research!

  10. Blitzkrieg had a stoneware bowl. We accidentally broke it and replaced it with a ceramic dog food bowl. I can't confirm if there was lead in the glaze, but I suspect there is. Blitzkrieg's eye clouded over and he was having vision problems. Since he only has one eye - this is even more disturbing! I started using the regular ceramic food bowls we human's use for Blitzkrieg's food. His eye cleared and his vision is back to normal.

  11. We actually use a surgical stainless steel bowl from our own cookware set. Safety First :)

  12. I love the stainless steel bowls. I bought one from www.snoopyspets.com that has two bowls in one. They have a hard resin plastic outside with stainless steel bowls on the inside for easy cleaning. They are great.

  13. I shared this article with my clients on my fan page and twitter acct...thanks for the great article..

  14. We use Pyrex glass bowls. Any thoughts on those?
    Great article! I will be sharing!

    ReplyDelete
  15. Hi Bicycle, thanks for barking by!

    While generally speaking we understand that Pyrex is safe and non-leaching, we do have a few concerns that would prevent us from using it.

    It can chip, being glassware, and if exposed to extreme heat and cold can become a little more unstable and have more potential to chip or crack. Glassware is safe, but we like durable too, which is why we think stainless steel is the overall best choice.

    Hope that helps!

  16. To choose the right size, consider that dogs drink approximately up to 25 ml per pound per day. That comes out to be a little less than an ounce per pound. So if you have a 10 pound dog, make sure your bowl holds at least 10 ounces.

    ReplyDelete
  17. Great research on the different types of dog dishes. I noticed there was no glass option. But I think I am going to switch back to a metal dish. I do see how it would be the safest.

    Also I notice that most people don't clean out their dogs dish every day. I don't understand this. Just a thought I needed to say.

  18. My father has always warned me to avoid using a stainless steel bowl because it can gradually reduce the dog's sense of smell. Does anyone know of any research on this topic or is this just an old wives tale?

    ReplyDelete
  19. Hi Anon...we've never heard of stainless steel affecting a dog's sense of smell. But we do know that it's really the safest dog bowl to use. My guess? It's an old wives tail :)

  20. I recently bought a PetCO brand stainless steel dog bowl but noticed a WARNING on the sticker "NOT for human use. For pet use only." Yikes! I don't like that. Any other brand recommendations for bowls that are safer?

    ReplyDelete
  21. Hi Gina, I don't like that either!

    Our suggestion would be to return the bowl for a full refund, and go on a search for a healthier bowl.

    Here are some ideas to find the best quality of stainless steel bowl for your pet:

    Try first to find a SS bowl that's made in the USA (it won't guarantee that it doesn't contain radioactive material or lead, but the chances are much less likely.)

    Second look for a SS bowl that is of heavy gauge (22 if possible) or has a series indicated at 300 or so. These numbers are indicators of higher quality stainless steel.

    Find out the manufacturer of the potential bowl you are interested and call them to see if they have been tested for lead/radioactivity. And that they are safe for human use. A good quality company will have that information and freely share it with you. If not, time to move on.

    Good quality SS products will have information stamped on the bottom that provides information, i.e., made in USA, gauge, etc.

    You should also read our other post about radioactive pet bowls recalled by Petco: http://blog.raiseagreendog.com/2012/07/is-your-dogs-stainless-steel-bowl.html

    I hope that information is helpful!

  22. Great article. My dog won't eat out of a stainless steel bowl. I am using some bamboo bowls, but those weren't discussed.

    ReplyDelete
  23. Ahh, yes, bamboo! A good alternative source if stainless steel isn't a option for your dog. Just like anything however, I would see if you can find out from the company if they are made in the US with materials grown without the use of chemicals in the US. I just worry about pesticides, insecticides, herbicides and potential additives leaching if made in the US where they may use them, or China or other countries where it may be difficult to find out. Just a thought. But yes, a very sustainable option! Good for you!

  24. I use whatever "cute" dog dishes I want and put a "human" stainless steel bowl in it like a liner. SS mixing bowls come in all sizes and some places have restaurant supplies that sell to the public. I pop the bowls in the dishwasher every night with dinner dishes to keep them clean. No fuss!

    ReplyDelete
  25. So what is the brand you recommend for safe Stainless Steel pet bowls? I see your criteria, but surely you have a brand you researched and trust. Which brand is that?

    ReplyDelete
  26. Hi Rachel, thanks for contacting us. We don't have any specific brands that we recommend. but doing a quick internet search we found only one company that actually indicates that their bowls are made in the US. http://www.basispet.com/

    They meet all the criteria I explained in my reply to Gina's comment (just above about three comments). They also say that they test their bowls for heavy metals, but I didn't see that they test for radioactivity (which would require a Geiger Counter). But you could call them and ask, it's a fair question. Good luck! And let us know if we can help further.
