Check his mouth as spaniels often get a condition called lipfold pyoderma. When my spaniel had it, we couldn't even stand to be in the same room as him The easiest way to tell he had it (other than a trip to the vets) was to look at his bottom lip. The skin folds where his top teeth touch the bottom lip was very red. We had no idea that was what was causing the smell. After an antibiotic injection, the smell was gone within a day.
That's it really in a nutshell. He is a 1 year old cocker spaniel and despite him having 2 baths yesterday there is still a dreadful smell coming from him--but l don't know from where,
Not his fur nor his ears nor his breath or bum--but it is truely repulsive. He is not unwell no change in diet and bowels okay. Was thinking of taking him to the vet on Monday. Any ideas???????????????
