So Nessa had her spay this morning! She did great, but now she's at home with me and putting up a major fight to everything. I have to give her pain meds (via syringe) and she absolutely refuses to let the syringe anywhere near her face/mouth. I can tell she's in pain, and I really want to give these meds to her; but she wont let me. I'm hesitant to picking her up or making her move around, but I just can't get the syringe in her mouth! She did a couple jumps trying to avoid me, and I think she hurt herself, so I've given it a rest for now. Also she wont eat anything. How long should I go before I contact the vet on this?
