I've been thinking about getting Missy a life jacket because this summer I want to take her to the lake and waterfalls with me and the family, also we plan on camping a at a waterfall with Missy. She has only been in water deep enough to swim once and she got tired quickly cause she never really swam before. I would like to be able to go out further and stay in longer instead of going back to where she can touch every few minuets. Should I get her one? Has anyone else gotten a life jacket for there dog? If so do you like it, does your dog like it, does it work?
