Yea- I know it runs rampant in our sighthounds, had one shepherd that had it, and although its just a mention in the breed standard- the lack of liking cold or not tolerating it is one of the biggest indicators of hypothyroidism. Make sure they do a full paneled test. I posted above what all is included.. WE thought for months Femka was just a " delicate " borzoi- but it didnt sit right with me. Finally the 3rd time I asked the vet they tested her- sure enough!
BTW- since we put her on the medication- her coat is just beautiful- she is not longer cold, and gained a few pounds she needed. The pills do not make them gain weight- but it does regulate the food intake better. I have posted pictures before of what she looked like when we got her- the difference in her body then and now is flat out amazing. Even her attitude is happier!
