I would definately call your vet. Diggy was neutered Monday
and the vet said its normal on the day of the surgery for him to vomit and to limit his food but day 2 he should be over it and eating fine. I am sure they all react differently to anest. but to be safe especially if you hear weezing...Id have the vet give you some answers to be safe. When it comes to lungs and breathing ya just dont wanna mess around and guess....I hope he is feeling better soon and give him kisses from Bella and Diggy!!!
