I am glad Jaxon is doing better. Drowsiness when first starting anti-seizure medication is very common, but it usually goes away in a month or so after the body adjusts to it.
I recently checked into New Mexico law after a woman on another forum got a very sick puppy who turned out to be only 5.5 weeks old and sick with parvo. There is not much legislation in NM that protects either animals or buyers - no minimum age of sale law, no puppy lemon laws.
No states have laws preventing people from inbreeding, breeding dogs with genetic faults, etc. That's why it is buyer beware when shopping for a puppy. A prospective owner should do their due diligence and thoroughly research a breeder before buying a puppy from them.
