Our Chihuahua's come with a one year written health guarantee against congenital diseases and have been vet checked. We currently have males and females available in a variety of colors. Their vaccinations and de-wormers are up to date based on their age. They should be between 4 and 7 lbs; best guess 5 lbs as adults. They can be registered with ACA. This particular liter was born 5/12/10 and we are asking $550.00 for them. We do deliver at $1.50 per mile or $300.00 for shipping. Our puppies are all treated for giardia, coccidia, ear mites, and worms. If you have any other questions or concerns feel free to call 973-652-7758 or stop by 380 McLean Blvd. Paterson, NJ 07513. Thanks for looking at our babies!!
