So my fiance and I are getting married this saturday, and his mother booked for us a 2 week honeymoon overseas (which is another story, entirely). We've got the dogs all squared away (they're being boarded at the vets office in the deluxe suite, together). We're having a friend house-sit and take care of our guinea pigs while we're out, which is all good.

My question is actually our house sitters question that I don't have an answer to, so I was hoping y'all might have some insight. Our friend brings his own dog with him everywhere, and was planning on bringing her with him when he's at the house. He said he would just keep her out in the yard, but I feel badly for her being stuck outside all the time. I wasn't sure if it would be okay for our dogs to bring the other dog in the house while we're out. His dog is vaccinated, I just wasn't sure if the smell of another dog in the house would be bad or upsetting (whatever verbage would apply), if they don't know the dog and they've been out of the house for 2 weeks.

Any advice would be appreciated!

I don't see any problem with letting your housesitter's dog in the house while your dogs are away. When they get home they may smell a strange scent, but as long as there is not some strange dog physically in the house when they get home, there shouldn't be a problem. They will probably just sniff around for a while until they decide that there is no threat there. I would think that they would find the whole yard more disturbing as the new dog will have marked the property, but they will just re-mark it as their own anyhow.
