I have 3 of my own dogs, the biggest being 100 pounds. I can run with energetic dogs or take it easy with older dogs. I have no problem giving medication to dogs or following a strict diet for dogs who require one. I'm strong enough to lift the biggest dogs in case of emergency and a run to the vet is required. I can walk multiple dogs at once. I'm not afraid to break up any altercations between two dogs. I love all animals but especially dogs. My oldest dog is 11 and requires medication and special diet. My roomate is a vet assistant so if i have any questions with medicine or something she would be happy to give me the information i need.
