I've had dogs at least 10 years, all of them usually small dogs but I have taken care of bigger dogs before. I'm home 3pm-10pm to babysit my niece but she also loves dogs, car rides, she is super sweet. She is priority, but dog boarding is not a problem as long as your dog is okay with babies. I would not mind training dogs, I helped train my friend's Lab puppy. I do have an open back yard but that shouldn't be a problem as long as you provide a leash. I have two chihuahua mixes that bark but are very sweet, and they are crate trained. My grandma lives with us, she loves and has wanted a big dog but my dad prefers small dogs. I have a 12 year old cat, he is nice and usually keeps to himself. I love dogs and would love to spend time with all the doggies!
