My dog has always been friendly and easy going but has started to get really aggressive to one particular dog that lives near me
He has never actually attacked it but yesterday my mum took him out and he actually attacked the dog and the owner fell over trying to separate them
This other dog is lovely and gentle so I have no idea why my dog dislikes him so much
Any ideas why a dog becomes aggressive out of the blue?she said she will
Report him to the police if it happens again.
He’s always been fine but has become a little bit more narky with other dogs too recently but not to that extent
Any advice would be much appreciated
