Plastic, ceramic, stainless steel, which dog bowl has the most bacteria? See if it’s the one you have at home

Drain the water from the dog’s water bowl, then flush it at the faucet, put some water in it, and give it to the dog.

Most dog owners do this, just a bowl of drinking water, and there is no dog food such as smelly things, how dirty can it be?

According to the NSF (Public Health and Safety Organization),

With the most bacteria and dirtiest household items in the home, the dog bowl ranked fourth

, almost squeezed into the top3 (top3 for kitchen rags, kitchen sinks, and your toothbrush holder).

Pet toys ranked 7th

, the dog bites dirty toys, and it is cleaner than the dog bowl for eating and drinking.

It’s not scary to have bacteria, but which water bowl has the most bacteria in it, and what harm do they do to the dog’s body?

Dog water bowls are strange, and there are no more than three commonly used by owners: plastic water bowls, ceramic water bowls, and stainless steel water bowls.

According to a study at the 69th annual meeting of the European Union of Animal Science, the number of bacteria in the dog’s water bowl is inextricably linked to the material.

Plastic water bowl

The researchers tested plastic, ceramic, and stainless steel bowls and found:

Plastic bowls have the most accumulation of bacteria

。 Plastic bowls are easy to scratch, scratches these small gaps are a good place for bacteria to breed. In addition, plastic bowls can also fade some dogs’ noses.

Some dogs are sensitive to plastic containers, and under the continuous stimulation of plastic water bowls, Plastic Dish Nasal Dermatitis (plastic bowl nasal dermatitis) can also cause the dog’s nose to fade and the lips may also be swollen. Certain chemicals in plastic bowls can inhibit the production of melanin, which in turn causes

The dog’s nose slowly fades

Pet doctors also advise: if you want to keep its nose beautiful black, it is best not to use a plastic water bowl. No matter how good the shape and price of the plastic water bowl is, it is best not to give it to dogs.

Stainless steel water bowl

Is the stainless steel water bowl the king of cost performance, cheap and hygienic? No, stainless steel water bowls are no better than plastic water bowls, fifty steps laugh a hundred steps.

Ceramic water bowl

The result of the ceramic water bowl is a little better than the previous two, and there are fewer bacteria attached to it. But!

Harmful bacteria prefer to inhabit ceramics

In this advanced material, they are more likely to survive and reproduce on the surface of ceramic materials. These picky harmful bacteria are also well known, such as E. coli and Staphylococcus aureus.

The conclusion: ceramic bowls> stainless steel bowls> plastic bowls. And it’s best to choose

White ceramic bowl

Colored ceramic bowls may contain harmful chemicals such as lead that can cause kidney, cardiovascular, and some neurological disorders.

But the longer food and water remain in the bowl, the greater the number of bacteria. The longer the time, the more significant the number of bacteria, until the water bowl is saturated with a number of bacteria, and slowly stop multiplying.

It is said that washing hands before meals is because people’s hands are used very frequently, and most of the affairs are inseparable from hands, so they are contaminated with a lot of bacteria. And dogs are accustomed to mouthing, eating, coquetry, making friends and even fighting, can not leave the mouth. The most contact with the dog bowl is also the dog’s mouth. When drinking water, various bacteria in the dog’s mouth are transferred to the dog bowl.

The unfinished water in the dog’s water basin carries their saliva, and dust and hair in the air will also float into the open water bowl, so suitable for the environment of reproduction and reproduction, bacteria are easy to multiply in a short time!

Dogs gnaw furniture, play with toys, play with their owners, and carry germs from water bowls around the home. If it is a child with poor resistance, exposure to these bacteria, illness is inevitable.

No matter what bowl you use,

Brush and disinfect regularly

, you can avoid the accumulation of bacteria in the dog bowl.

How often do owners wash the dog dishes? Seeing this, isn’t it time to wash the dog dishes?
