One simple thing I just read about to help prevent your dog and cat from developing urinary, bladder, or kidney infections is to be vigilant about washing out the water dish with hot/soapy water and changing the water atleast once a day.
Bacteria can grow quickly in the water and not just in hot weather.
The article mentioned some nice dishes that are made from recycled plastic. However, I believe stainless steel dishes are the best. Years ago, my cat Oliver developed what the vet called “feline acne”….little bumps on his chin. I was told that is something that is more common when the animal eats or drinks from plastic dishes.
And seamless dishes are the best, too, as bacteria cannot accumulate in any creases.
