Taylor a 10 year old Queensland /Border Collie and Jody a 15 year old Terrier Mix - 5 years ago Jody could not walk, she had loss the use of her back legs due to arthritis, but with meds and physical therapy and compassion from her vet, she runs and plays, just has, as the vet says a "little hitch in her git-a-long. Taylor when she was 6 weeks old had to have surgery to remove a "screw worm" that had burrowed into her neck. Her vet said he had only seen that happen on livestock. I bought Taylor from a family that had the pups on land shared by cattle. Her vet kept the worm in a jar.Talyor is so attentive and loving, you can tell by the look in her eyes and Jody is a walking miracle, and at her age a bit set in her ways. I love both my babies. I couldn't ask for better children. Around my house you can tell it's dominated by females.
