Phoebe was really acting sickly last weekend... terrible panting, respirations up to 35-40 breaths/minute. Very scary stuff. We had no idea what was wrong. I called the emergency/on-call vet and she talked me through it and explained that this was panting and NOT respiratiory failure. She had us come in the next morning and we did. She said that Phoebe was probably just rough-housing too much with a young puppy and hurt her back. She gave her Metacam (an NSAID) and within 24 hours the panting was gone and Phoebe was back to 100% normal.
They did blood work which was Normal. In this video, you can hear the vet's voice mail to us about Phoebe's blood work. I spoke with Dr. Mlekoday the next day and she confirmed that this was probably a lab glitch (because the sample was more than slightly hemolyzed). Still, to be 100% sure, we're repeating blood work in 2 weeks.
