Why in the world would my dog's breath smell like fish?

His breath smells like fish. He doesn’t yelp or anything when he eats his food… could it still be a bad tooth? He also eats very well, if that helps with anything…

Answer #1

Could be a bad tooth … or something caught in between his teeth. There are drops you can get that you put in his water to help clear up bad breath - give that a try, and if it doesn’t help, then consider seeing a vet.
