My baby boy (he will be 11 months old in four days) has started to get aggressive. He is neutered.
He is perfectly fine with dogs he has known since early puppyhood. He is good with the dogs at daycare and at the park. However if the dog is walking by him on leash he loses his mind... Lunging and barking.
Last night we tried to introduce him to a puppy and he tried to bite her! Then today we tried to introduce him to an old dog and we had to pull them apart they were going at each other.
He also barks and lunges at joggers.
We are working with our trainer and using the book Click to Calm, but is this just the teenager phase or something worse? What more can we do?
Any advice please. I'm just about in tears over this behavior lately.
