I have dogs stay at my home, which I enjoy very much. However, lately my own dog, a male Irish Setter, has shown some issues with food to our guests. I am worried that he might actually hurt a guest dog. Or, what happens if a guest dog does the same to one of my own dogs? Is there any coverage? How is this handled?
In addition to what the others stated, I think it's important to walk all the dogs together in general, but especially if they're having issues with each other. This helps them bond and get used to each other and build a more cooperative atmosphere, rather than competitive. I've always fed dogs in the same room, but I make sure they're facing away from each other and have as much space as possible to eat.
Your dogs and the guest dogs are both covered under Rover's pet insurance, however there is a $250 deductible that you or the owner would have to cover (legally it must be paid by the owner of the dog receiving care, and it would be up to you and the other owner to negotiate whether some of all of that cost should be reimbursed by the other party depending on the situation). There is always the chance of injury, but as Haley said, be proactive about preventing scenarios where resource guarding is likely to occur. Even as early as the meet and greet, discuss the guest dog's history with guarding behaviors, and let the owner know what your prevention measures are, and stick to them. Since you have a dog who guards, be sure to feed all dogs separately and do not give treats while the dogs are together.
And it's worth considering whether or not your dog is comfortable with sharing his home with others as frequently as he's being asked to. It's his house, too, and if he's developing more guarding issues with guest dogs, he may be doing his best to tell you that he's unhappy with this arrangement, and it might be a good idea consider whether the stress it puts on him is worth it. My older dog does really well with guests, but I know her really well, and we do take breaks if we have a busy few weeks, because eventually she just wants time to chill without all the other dogs around.
I agree with Laura R. it's important to know the habits of your own dog first, Know his/her temperament, his welfare comes first. He does ok, but too many he starts to really get annoyed but he is extremely non aggressive. IF you have an aggressive dog, versus an extremely friendly one, it will be harder to have guest dogs with a naturally aggressive dog!
I have a rover sitter I book sometimes just via text. I just paid a $1500 vet bill because her dog bit mine while in her care. I wish I had gone through the website. :(
I always feed guest dogs in a seperate room and make sure there aren't any food/treats around to be fought over- that should allow you to manage any resource guarding behavious that your dog or guest dogs are showing.
In terms of coverage, I believe the Rover dog and your dog would be covered if anything happened to them.
