She may be in pain.
My vet gave me Rimadyl, for Riley and told me to give it to him day and night until it was gone, even if I didn't think he needed it.....
I didn't have to use anything when I was able to watch him. He wasn't really a licker or scratcher. I used the onsie at night and when I was at work.....only cause I couldn't keep an eye on him......
At night, he was in his x-pen at that time and would cry when he had to go potty so I would just let him out, unsnap him, he would go potty, then I would put the onsie right back on and back into the x-pen he would go.
The Vet did send me home with a cone, and she said,he can pee, poop, eat, sleep, and do Absolutely Anything he normally does, and not to let him make me think he couldn't. LOL!!
Sending positive vibes for a Speedy Recovery!!
