We just had our 1-year old yorkie spayed last thursday morning. It's now monday night. She seemed to do great, not much lethargy, a little less appetite, but nothing that caused any concern. We've kept her collar on up until yesterday, but now take it off when we can watch her closely. She's pretty spunky, but we've kept her calm and laying around most of the time. She hasn't been picking at her stitches.
Just tonight, we noticed she was a little shy and a bit lethargic. She just crawled into her kennel alone to lay down, which is very unlike her. If we're around, she is always right by our side. I noticed that she has some swelling on the right half of her abdomen, just above her privates. I read that some swelling is normal around the incision, but this isn't even close to the incision. The incision is probably 3 inches higher (which surprised me, our dogs in the past had incisions further down), just below her sternum. Any ideas what this could be? We're debating a trip to the emergency vet or giving her a night to see how it goes and taking her to our regular vet if need be. She does not seem to be in any pain, I've pushed lightly on the swelling and she didn't react. It is somewhat firm, but could be fluid. Thanks!
