There are exceptions to everything
When I bred Lhasa's, Hsun-Ni my little stud took his role as daddy very seriously.
When we brought our Lhasa's to the USA from England, we had to stay with my father in law who didn't allow dogs in the house
so we had to leave the dogs in kennels until we could find a house and move in.
This was in June. I specifically asked the kennels to keep Tee-Nah and Hsun-Ni apart as she was due to come in heat and I did not want her to get pregnant this cycle - last litter she had to have a C-section so I did not want to risk her getting pregnant and having puppies in boarding kennel.
It was August before we could move into a house, and as soon as we got the phone on I called the kennel to let them know we would be picking up the dogs as soon as all our things had arrived in a few days.
I got a call that evening that Tee-Nah was having puppies! (now we had visited the kennels weekly to check on the dogs and there were no indications that Tee-Nah was pregnant, and we were assured that they were keeping Hsun-Ni and Tee-Nah apart.
Apparently that day that Tee-Nah had the puppies the kennel girl had left for the day, then she remembered that she hadn't put the "hot spot" ointment on Tzu-Hsi, our other female. So she went back. When she got back Hsun-Ni was going crazy to get her attention, barking at her, when she went to check, he ran back to Tee--Nah - she was giving birth! They wouldn't have known until the next day if Hsun-Ni hadn't alerted the girl when she went back.
We went and picked up all the dogs (the 3 Lhasas and the 2 Yorkies and Tee-Nah's puppies )that night and brought them home. Hsun-Ni was watching over and protecting Tee-Nah and the puppies.
Even after we brought them home he was protective of Tee-Nah and her puppies.
It didn't surprise me, because when we got Tee-Nah she was a tiny "runt" who wasn't expected to live (the breeder was just going to let "nature take its course, Tee-Nah was the smallest of a large litter and the mom wasn't feeding her), we begged to have her to try and save her. Hsun-Ni was only about 3 months old at the time. I sat up every night the first few nights with Tee-Nah on my lap and feeding her drop by drop from a syringe. The vet didn't think she would make it. When I had to put her down I put her in the crate with Hsun-Ni, in the morning I would look and Hsun-Ni would be licking her clean and waking her up. He was actually acting like a Mommy to her. The two of them became inseperable.
So, I wasn't surprised that he was watching over her in the kennel. But they weren't supposed to be together!
There were 6 puppies and we lost one after a few days. But the other 5 all survived and were healthy.
