We're in need of a dog trainer to work with us. Might anyone have an incredible recommendation? We've got a wonderful chihuahua we rescued at 7months old, he's now 2.5 years and has some bad habits. We've tried everything, willing to try another trainer. He is aggressive toward dogs he doesn't know, and nips at strangers' legs when they're in our home.
Otherwise he's a sweet little man who is also obedient.
