I’ve known Peter for many years. He grew up around horses and dogs. His family ran a Dude ranch in Montana. As an adult, he always had cats and dogs, one or more, rescues and thoroughbreds, young and old, in multiple combinations. His pets were healthy and well-behaved. He comprehends dog and cat behavior and body language without anthropizing them. For instance, my dogs were house-trained and had quick and easy access to a large, secure yard. I was perplexed when one of my dogs pooped inside when she had occasional diarrhea. I thought she was eating something that caused indigestion. I ignored her behavior for a while, but when it persisted, I talked to Peter about it. He told me it was her way of getting my attention, of asking for my help. I took her to the vet. She has an anal gland abnormality that is now well-treated with twice-daily bulk laxatives. In retrospect, her behavior was clear, but at the time, I hadn’t interpreted it correctly. I remember, when Peter already had three dogs, he inherited two poorly trained, adult Yorkies from his aunt. One 3-year-old Yorkie reportedly “refused” to be house-trained. The other 5-year-old Yorkie stubbornly marked his territory inside the house which got worse when he started living with Peter and the other dogs. With considerable patience and persistence, he eventually succeeded in changing their strongly engrained behaviors. The “untrainable” 3-year-old Yorkie became house-trained, and the other Yorkie stopped marking inside. I was amazed and amused when I saw how the younger Yorkie jump up, balance on four paws on the threshold of the large doggie door, lean forward, and sort of fall through the doggie door to get in and out. They became well-behaved, confident, and integrated pack-mates.
