I have experience with all size dogs. I grew up with yorkie, Saint Bernards, Rottweilers, huskys and German shepherds. I can walk any dog of any size as long as they are trained to behave. I can only pet sit one dog at a time. Weight limit is 25 lbs and under. My condo rules. I have a amazing property for walks and I have a great area of grass to play in/ dogs to potty and I have potty bags. I will except male dogs as long as they are neutered. Lulu had a step brother. He passed away last year at 16. So, she is very social and easy going. Dog doesn’t need to be crate trained as long as he/ she doesn’t eat furniture or chew on things they shouldn’t. If I needed to go run errands would be the only time in crate if I could bring them with me and lulu
