What type of bowl do you have. I know that sometimes plastic bowls can fade the colouring of dogs noses.
We use stainless steel...way easier to clean lol.

Simba used to reverse sneeze alot, it may just be allergies.
Yea, I was thinking that it might be allergies. He's had it for a while and the vet said it should go away. He said that if it doesn't, he'll have to have a tube go in him.... I sure hope not lol.
