Trevor and other dogs

[sallydog14]

Hi. I've had Trevor about 4 weeks now and he is an adorable dog who is so loving but he has just started to have issues when I leave him and when we are out he is'nt as friendly with other dogs as he was at the beginning. Has any one got any ideas please.
I have to muzzle him now when I leave him because he has cause alot of damage. I'm still waiting to hear from my insurance company! And when we are out I've just started to muzzel him because of his aggressive behaviour. Help any ideas please? I am hoping to find dog training classes for us to go to.
