x-rays today ...negative. Then where's the arthritis? His spine? Spondylosis is painful but that shows up radiographically. Arthritis isn't there 1 min and then gone suddenly.
heart good, not enlarged. Great but may not be the whole story. Have you fed grain free dog foods? Did they measure his pro-BNP (cardiac enzymes) to see if it's his heart?
blood work done again...results tomorrow. Tick borne diseases all negative? (Lymes, Anaplasma, Erhlichiosis, RMSF). Any anemia? Any increase in reticulocytes? Splenic hematomas are common in older labs and bleed internally. Ultrasound can diagnose that and many more things easily. Any new abnormalities?
gabapentin and assuming blood work is normal a new drug added...carprofen. Why gabapentin? It's useful for neurological pain (pinched nerves, slipped disc, etc.) but it's also a sedative. Carprofen is for pain. Is he painful or is he depressed?
He had slightly elevated liver enzymes 1st round. That was the only thing that came back abnormal. Waiting to see new test results. Galliprant is better than carprofen for pain for dogs with liver issues and all older labs have liver issues to some degree. Another reason to get an abdominal ultrasound by a specialist.
the ole fucker loves going to the vet...he was his normal self once we got there. If everything is negative it may be time for a referral to an internal medicine specialist.
