I have experience working with a variety of different dogs, from calm and relaxed to energetic or nervous. My family dog use to enjoy running freely and playing with other dogs, sadly due to an attack he got very nervous and protective. I understand some dogs get nervous and want to go after others, working with him, I was able to improve his behaviour and get him more comfortable around dogs. I have also taken care of a very energetic working dog. She never stopped. Thankfully I was able to create a nice calming environment, including a very long tiring walk, to get her to settle down and not be worked up all the time. I know no two dogs are the same and each dog needs their care tailored to them.
