We adopted our dog Stitches (see avatar) at 1 1/2. Our Vet's wife was looking for a good home for him. I'm quite certain he was at least half Lhasa. Best dog we ever had and he lived to just two weeks shy of 18. He was quiet, gentle, intelligent, brave and stoic. He was extremely obedient. He took life very seriously. He had trust issues and we believe he had a very hard start to his young life. He was frightened of men and children and gravitated to women. He was kind to our cat but very aggressive and would pick fights with other dogs. He had no problem with me being the Alpha dog in our little pack but I had to work on him a little bit to not be jealous or nippy with my husband. Your little guy has been through a lot. With time, continued security and love, he should work in well.
