We are "temporarily" dog sitting for a relative's dog because he's been in and out of the hospital a lot lately. The dog (who's between a year and a year and a half) had been to our house multiple times before this extended visit, but always with the owner. He's been here two weeks with no problems....until this weekend. Late Friday night I caught him peeing in the hallway, and quickly realized he had left a trickle trail down the entire hallway from living room to office (a trail approx. 10 feet long and 4 feet wide). It took us forever to find it all and soak it all up with paper towels (the trails were light enough they didn't leave wet puddle prints on the carpet). We have since put down Pet Fresh Odor Eliminator because we don't want our pets (a dog and 3 cats - who have NEVER had an accident in our house) to start leaving messes. This afternoon we had company. The dogs were in and out of the house. Just before the last couple left our friend commented that she thought one of the pets had an accident. Sure enough. He had left roaming trails of pee through our entire dining room and into the living room. Luckily, mostly on linoleum this time, so much easier to clean. However, he also managed to pee on the side of my husband's recliner (this dog is fixed and does not lift his leg). I don't understand why he's just starting to have these accidents, and am very frustrated that he pees over such large areas. It would be so much easier to clean up if he just kept it in one spot. I guess I'm just wondering if anyone has any suggestions or ideas about why this might be happening (and what we can do to prevent it from happening again). This dog could wind up being with us for quite a while, and with school starting next week, I'm not looking forward to all the extra clean up.
