They're actually called "Deer" chihuahuas, not "Reindeer" chihuahuas. It's a term developed by "breeders" who breed the long-legged, lanky type of chi (think Taco Bell dog) as opposed to the Chihuahua as it looks when bred to the standard. The dogs that are bred to the standard are referred to as "Apple-headed" chihuahuas.

My little Poodle had the same symptoms as your dog & it was a seizure...just one though. She also had Pancreatitis & was a sick baby. She did recover though...after a 4 day stay at the Vet.
When she had a seizure, she laid on her side, kicking & thrashing her legs, foaming at the mouth & lost her bodily functions. She stared & her eyes were huge. She was out of it for about 4-5 minutes. I freaked, but my friends were here & took over, than we wrapped her up & took her to the ER Vet. Of course this happened New Years Eve..at night when my Vet was away. After many tests & scans & treatments, she did get alot better. Thank God.
Please take your dog to a Vet so they can see whats causing this. I see that you love your dog like we all do here & thats great. I know that you will do whats best for him.
P.S....what is a Reindeer Chihuahua??? My friend rescues them but never heard of "Reindeer".

It definitely sounds like some sort of seizure activity. I would have him checked out by a vet. It doesn't necessarily mean that he is epileptic, since chihuahuas are VERY prone to hypoglycemia, which can cause seizures. It might not amount to you having to give him an anti-seizure drug every day, if it's caused by hypoglycemia you can combat the seizures by giving her several small meals a day instead of feeding her once a day as you would an adult dog. Because of their small size and nervous demeanor, chihuahuas have a high metabolism and need to have food periodically during the day to accommodate that metabolism. Check with your vet, he or she will examine your dog and advise you accordingly, but my money is going to go on hypoglycemia.
Please post back and let us know what the vet says.
