I have owned and been around dogs all my life, have cared for neighbors and families animals. Check frequently to make sure they are cared for. I do not run with animals but walk. Hoping to dog walk enough to where I can start to run. I have no issues walking dogs in cold weather as long as the dog can also handle the weather. I can handle multiple dogs, although my max is four at one time. I do prefer medium to small size dogs, though have no issues with larger dogs. I will always treat your animals as if they are my own and follow all instruction on how to care for your animals. I also have a very flexible schedule to work around yours.
