Hey all.
My dog is 8 years old and getting grumpier as the years go by. She has always been highly strung/anxious and is a breed that needs lots of exercise but it's getting harder to give her off lead time because she is just so grumpy around other dogs. We walk in woods for an hour or two at a time and whenever we're alone she's off lead but I have less and less confidence in her when other dogs are around, she will snarl and growl and get into fights (although doesn't bite).
She is very dominant with my other dog, who is male and bigger than her! He adores her and just rolls over, so it works for them but she thinks she can dominate anyone.
She's never so much as growled at me or kids (She's currently laying with her head on my knee snoring like a good un) but she went mad when our postman came the other day- she knows him, he always fusses her, he's lovely. Then today we had friends round and she either growled at my other dog or at their daughter - I wasn't close enough to see which.
Overall she's getting grumpier and it worries me.
She is well exercised.
Vet can't find anything wrong with her.
Any thoughts wise ones?
