You may be asking yourself: "Isn't there just one type of dog bowl?" The short answer is no. The long answer to this is in this blog post about different types of dog bowls.
If you're often on the go and like to take your dog with you, then you should definitely have one of these in your inventory. Travel bowls are usually made out of silicone, nylon, or polyester fabric to enable easy cleaning. The great thing about them is that they're collapsible. So as soon as your dog is done eating or drinking, you can fold them into a flat, frisbee-like shape and you won't have to worry about it taking up too much space in your bag.
Elevated Dog Bowls
Keeping your dog food bowl on a slightly elevated surface can be helpful for tall dogs, as well as for those who are disabled or recovering. The elevation helps to improve comfort and reduces joint damage in tall dogs. Moreover, they're great for preventing dogs from tipping over their bowls when they're rushing to eat out of excitement. It happens to the best of us.
Deep bowls are excellent for dogs who have long noises as they allow sufficient nose room. These steep-sided bowls prevent the dog's ears from falling into the dishes.
Shallow bowls are good for dogs with small noses and for puppies, the lack of depth makes it easier to reach the food. But keep in mind that it might get messy since the small rim doesn't stop the food from falling out of the bowl. To make cleaning easier you can put a non-slip mat underneath the food bowl and just wipe it off afterward. This also prevents the bowl from slipping around while eating.
