You own a Chihuahua? Then perhaps you can explain something. Why are most of the adult Chihuahuas always shivering? At least the ones’ I see are always shaking. Do they tend to have low blood pressure, or are they just naturally as hyper and nervous as a Hummingbird? I do know they can be very good watch dogs, at least to make noise at the unfamiliar squeak.
I have no idea why they shake. The fat one shakes constantly. And he suffers from hypothyroidism.
The other one only shakes when he is tired, cold, not feeling well. Tonight is a combo of cold and not feeling well. He gets constipated from time to time and makes the biggest show of it.
With the chis I had, it seemed to be the most obvious point of all...with their short, thin fur, they were COLD!
They’re a Mexican breed, and out in the warm Georgia sun, both of mine stopped shaking. Inside with the airconditioner, it would start.
