Cat, she moved here to NH from Texas with owners and a 1yr old dog. Once here, they brought both dogs to the shelter; Katie was 11yrs old. She came waddling out, dripping blood, with infected ears, gave me one kiss and that was all it took. We knew she had arthritis, turned out she also had bilateral hip dysplasia, hypothyroidism, bladder stones i n addition to arthritis and being huge. Thyroid meds, Core reduced fat, pain meds and eventually she got down to 26 lbs. She survived surgery to remove a hemangiopericytoma from her shoulder, lived a little more than a year more and died in 2011 at somewhere round 15 yrs of age. She became totally deaf a few months after we got her but she loved all adults but not the kids and she ruled the roost around here.
We had another sheltie at the time, Tucker was 20" tall nd 34 lean lbs. Was mistaken for an Aussie (he was a blue Merle)
