Sudden drooling during walks?
Our dog has started drooling during walks. He never drools at home or when we play with him at home. He eats his food normally and seems comfortable and happy at home, and he also seems happy on walks and walks along at a good pace. He is 9 years old.
It doesn’t happen on every walk, but it’s happening on most walks now. However, there are still walks where he doesn’t drool at all.
Has anyone else experienced their dog suddenly starting to drool during walks?
