Dog had surgery on cruciate ligament today, in the afternoon. We picked him up 6pm and he came out of the vets on 3 of his own 4 feet. Lifted him into the car and after a few minutes he slouched down and fell asleep, all pretty normal. When we got home we struggled to wake him and he was unable to support himself at all, not even sitting while I got my keys out. I carried him in and put him on his bed, he fell deep asleep again. It's now 1.30am so 7 hours since we got home and at least 11 hours since he last had a widdle. Vet gave instructions to restart metacam i the morning and his paracetamol and gabapentin tonight - needless to say he has refused a drink and had no food and therefore no painkillers tonight. He looks about every half hour to check I'm here and goes back to sleep, with a groan. Clearly in pain. The last thing I need is to waft food under his nose, for him to take it and then upchuck it, as usually happens when they eat before they are ready. But I've got no other way to get painkillers inside him!!! It sounds like this isn't what the vet expected for tonight but does anyone have any experience of an animal still comatose 12 hours post surgery? Obviously I'm not going to bed tonight and if there's no change I'll be on the phone to the vet as soon as they open. Just hoping for any reassurance.
