Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
Based on the signs you are reporting, your lass's breathing and behavior
is suggestive of has experiencing discomfort from her operation. In this case, if her vet did not provide pain relief to go home (or has and she is still sore), then it'd be ideal to ring them now and request they dispense an further pain relief for her now. I would just note that we do not want to give any human anti-inflammatories to her in this case. This is because most are toxic
to dogs. (And unfortunately those human pain relief options that we would use like Tramadol or Bupenorphine are prescription only). Even Aspirin, which we do use on rare occasion would not be safe (since it is a blood thinner and therefore isn't ideal after a surgery) in this case.
Overall, her signs are unfortunately suggestive of discomfort from this. Therefore, it would be ideal to contact her vet to address this for her and ensure that we get her comfortable with her ear.
