Terrier mix with severe aggression

I am about 3 weeks into Blair’s virtual program. My 5 year old terrier mix has developed some pretty severe aggression to humans (myself included) and other dogs, and I had no idea where to even start with addressing and correcting them. Blair immediately made me feel at ease and his confidence that he could help us took a huge, almost unbearable amount of stress off of me. He really listens to you and ive yet to ask him a question or bring up an issue with my dog that he didn’t have a solution (that actually worked) for. There is zero judgement from him and he’s able to understand and explain what is the cause of certain behaviors and actions, and how to correct them in a way that will click in your dogs brain, and that they retain. We’re still fairly early into these changes we’ve made and it is already like night and day with my dogs behavior, and he’s begun to develop a respect for me that was nonexistent before we started. Blair is always quick to respond to messages and is so patient with my constant questions and requests for calls. While I previously dreaded doing routine things, like taking him for walks, having people knock on my door, even picking up his food bowl and toys,I already feel so much more confident in how he reacts and how I can correct him. I can’t recommend this program or thank Blair enough!
