I'm sure she has been cared for, but to an extent. It looks like she never gets groomed or dewormed or pampered like a horse that old truly deserves. If she was truly a pet, she wouldn't live with garbage and eat out of a rusty "trough".
"Just old". Riight. Maybe that's why she can't put any weight onto her body (that can only be described as skeletal): her teeth are probably useless, as others on the news site have suggested. It doesn't matter how much he's feeding her if she can't chew it and digest it properly. Not to mention the abscessed tooth and potential worm problems. I wonder what this vet that is meant to come out will say. She is definitely NOT in 'good condition', you would think that any fool could realize that. Would it be acceptable if they saw an 80-year-old woman that was skin-and-bones? Would they just say 'she's old'? Her 'owner' looks to be in good shape despite 'being old', hmmm.
