I have watched my cousins three dogs multiple times. My dog goes swimming over there all the time and up at their lake house with her dogs and they play really good together. My old dog used to get seizures and at 14 I knew what to do. I have watched all different types in different age groups. Puppy age to almost senior age. Dogs make me happy. I got diagnosed at 18 with multiple sclerosis and being around dogs seems to be the only thing that has kept me content and happy with life. Dogs are the best thing that could be in my life. I have plenty of dog toys and treats to share. I've never had any problem with dogs. When they're happy I'm happy.
