I don't know of any here, but my Mom's vet did that for her when she had to put her GSD down. They had been his vet for 13 years and they were so sweet to come and do it at home for him and her both.
@vlabroski: Yes Virginia Hajovsky in Huffman did that for my Mother one time, and she also put my 18 yr old Chow mix down and came outside her place and did it in the grass for us because we didn't want my dogs last moments on a vet table. But she was both mom and my regular vet at the time and  dont think she will do it again being we havent used her in 12 years. Because we just moved back to kingwood a while back, and dont really have a regular vet out here, I cant find any that will even come out to the car and do it...again I don't like doing this on a vets table but wont have a choice, as its time.
