There is no breed I dont like, I am very big dog person. I have helped take care of pugs, Pit Bulls, lab mixes, chihuahuas and dachsunds. I have been around dogs all my life. I can take your dog on stimulating walks. Ive owned 2 dogs in my life, a currently 12 year old chihuahua/ rat terrier mix and a 1 year old Dachsund. Both are rescue dogs, which is one of the things I really like. I love rescue dogs, my mom owns a rescue dog, a shiba/ chihuahua mix. My aunt owns a pug purebreed, and a wire haired terrier. No dog is too difficult for me, if your dog likes jumping on people at 100 lbs... then I'll welcome it happily.
