@ownedbyspencer:
The vet will send us home with pain pills, but I'm hoping they'll prescribe some tranquilizers as a backup, in case she gets rowdy before it starts to heal. .
Nobody wants their pet to suffer, but pain is nature's way of telling us to take it easy. I think overdoing the pain pills can cause problems. I don't overdo the Bute with a lame horse, because in absence of the pain "warning" they are far more likely to cause themselves further injury. You don't want a pain free dog ripping out her stitches! (it happens).
Keeping her quiet will be challenging, no question. Possibly a little chemical help to tone her down might be a good idea, and with luck the vet will concur. It might be wise to try a calming medication now, as a trial, to see how she reacts. (not always predictable!)
