Cilla our 6 month old cocker was spayed yesterday. Other than a couple of normal wees when she came home at teatime yesterday, we noticed this afternoon that she has been trying to wee more but not actually producing anything other than a tiny drip. She is eating and drinking fine and she has had 2 small poos. She is taking anti spaying meds but could this be a urine infection? We're off to the vets in the morning but can't really take in a sample as she doesn't produce enough. Any thoughts?
