Our 9-month old Cavachon puppy is house-trained and very well behaved (for a puppy!). (We’ve had her since she was 7 weeks.) Unfortunately, she has just started peeing when we return to the house. When we walk in the door, no matter how short or long a time she has been left alone, she pees on the floor (or on our feet!). This has been going on for about a week. Even if we walk in and wake her in her bed, she pees. We then tell her to go outside (the doggy door is in the same room) and she tucks her tail and ears and goes outside and sits there a while, then comes back in. We don’t get to snuggle her anymore upon returning, and are constantly cleaning up after her! Any suggestions?! Thank you.
