I have grown up around dogs my whole life; Labs, collies, beagles and multiple spaniels! I’m used to their high energy and constantly being on the go. I also know what it’s like to leave your companion behind as you go to work everyday or away on a trip for the weekend. Afraid they won’t get enough exercise, training and/or brain training leaving them with someone like your sister who has a huge love for dogs but little experience in keeping them on the go and preoccupied. I have experience with exercising dogs, playing games to keep their brain occupied and just genuine play time. Any puppies that need help progressing is always a challenge but I am more than happy to help with that too.
