We had our dog fixed about 2 months ago. Every once and a while a certain pungent smell seems to be coming from his hind quarters, we though when we had him fixed it would go away, but it hasn't. It doesn't happen as often but it still happens.
He is a large dog(Lab/retreiver) and he is almost 16mthns old.
What do you think?
It is probably his anal glands. This is natural, unfortunately it stinks like dead fish. It is your dogs skunk gland. Vetcare
