Plain-English summary
A 7-year-old mixed-breed dog was brought in for severe lameness and pain in the front leg, along with a high fever. The vet found calcium crystals in the dog's joints, which indicated a condition called pseudogout, likely linked to a past Ehrlichia infection (a type of tick-borne disease). After treatment, the dog's symptoms improved, and follow-up tests showed no more calcium crystals in the joints. The dog is now feeling better and moving comfortably again.

Abstract
Calcium pyrophosphate dihydrate (Ca2P2O7.2H2O) crystal-associated arthropathy (pseudogout) was diagnosed in a dog. Clinical signs included non-weightbearing lameness, signs of pain on joint manipulation, and high rectal temperature. Arthrocentesis of carpal joints revealed extra- and intracellular crystals containing calcium. The suspected cause was polyarthritis secondary to chronic Ehrlichia infection. Results of joint tap performed after resolution of the clinical signs were negative for calcium pyrophosphate dihydrate crystals.
