Hi, I have a lovely 11 month old black lab puppy. She has a lovely nature and is Well behaved when we are out and about. She does have some anxiety issues which we are gradually working through - mainly people coming into our home she barks madly at, which has been challenging. She has just finished her first season and has been acting very oddly since- she went off her food which I do understand but she hasn’t regained her appetite and this animal normally eats everything in sight!! As well as this she is refusing to let my older children walk her - she slams the brakes on and will not go, if I am there she trots out quite happily. This is so weird as she loves her walks and enjoys playing with them. Any thoughts?
