A few minutes ago I had found my 6 month old boy mutt with a bloody nose! He as only been back in the cage for about 10-15 minutes and he was perfectly fine before! His breathing sounds kind of muffled and he is sneezing a lot. His breathing and sneezing may just be from the blood in his nose but I am not sure! I also have no idea why his nose is bleeding I dunno of his brother scratched him or what! Their also seems to be something in one of his nostrils. Does anyone know what could have caused this or what to do? I plan to call the vet but he is close at the moment.
