I am a dog trainer that has owner trained 6 assistance dogs for their owners , this being 4 of the dogs being “stubborn” breeds. I also own a belgian malinois and have owned a cane corso, i also have great knowledge on a dogs body language, about 2 years ago i also partly worked in a dog groomers in leeds. It is also important to say i train dogs with what works for them. Not every training method works the same for different dogs, wether this is positive reinforcement or balanced training. I also understand if people have reactive dogs and there would be 0 animal contact. I also used to own reptiles and have good knowledge about them aswell!
