Our Maltese's come with a one year written health guarantee against congenital diseases. Their vaccinations and wormings are up to date based on their age. They should be between 4 and 8 lbs; best guess 7 lbs as adults. They can be registered with ACA. This particular liter was born on 2/21/10 and we are asking $610.00 for males and females. We do deliver, at $1.50 per mile or $300.00 for shipping. 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!
