So I’m over at my grandma’s house for the first time in a while and my grandma’s dog’s back is very hard to the touch and stiff. Also whenever I touch her on the stomach or back she yelps and barks until I remove my hand. Her coat is grown out and I’m trying to convince my dad to take her for a trim but to no avail. I really don’t think my grandma should be caring for this dog anymore but that’s not really my choice. Does anyone know what this might be or how I might help? (p.s. I’m only 15 so I can’t drive to get the dog groomed myself unfortunately.)
