No dog is too big or too small. I love them all! Have four dogs currently, different breeds. I live in house with six other girls so your dog will get plenty of love. I have always had a dog and was a therapy dog trainer for Ohio guidestone. I can run with the dogs and can play. I have trained my dogs but I wouldn't say I'm an expert. I'm good with dogs of all ages and can handle all ages. I do have classes in the mornings but am free different parts of the afternoon and evening. I own a car and am able to be flexible. Your dog would be in good hands with me I am a very bug animal lover.
