I have pet sat both dogs and cats. The most pets at a time were 3 very large and adorable dogs. I love pets of all kind and I have 2 of my own cats. They do not like being around dogs so they just stay away if there are any dogs over. I've never had any issues. We block off the upstairs with a baby gate so the visiting dogs and cats don't mix. I live with my husband who is a huge dog lover as well. I have an almost 2 year old daughter who is closely monitored around any animal. She is very used to both cats and dogs of varying breeds. I will be having a newborn in April and we already have a nice double jogging stroller so giving your pup attention and walks is no problem. I treat all animals as if they were my own by providing plenty of water, lots of walks, and the appropriate food according to their specific diets. Animals are not much different than babies and need all our love and attention! I will be the best pet sitter you could ask for! I'm excited to meet you and your special pet(s)!
