We are making deliveries on November 29th from Los Angeles to Sacramento for a delivery fee of $60 which is less than half the cost to ship live animals via airplane. Dropoff locations can be arranged to Sacramento or anywhere on the way. Please contact asap if you are interested in my hairless guinea pigs.

My Hairless Skinny Pig MHPC’s Lavender was featured on an episode of CBS’s TV show “The Doctors". It was aired on April 20, 2011 titled "Your Health in the Headlines". See the video in our "Featured Cavies" page.

When Breeding Baldwins:

Breeding age of sows:  It is very important to breed sows at the proper age of 8-11 months old and when they are well developed. They should also be a good weight and size.  This is especially true for the Baldwins as they are not the same as you would breed regular guinea pigs and are generally smaller in size.  We have been breeding them for many years and have never had issues with them getting a fused pelvis known as dystocia and it is likely a myth.  The pelvis does not fuse in older sows, it stiffens making first delivery at over one year of age more difficult. It is more common in over weight cavies.  If you breed them at a younger age you will have complications of having weaker babies and your sow may die or have complications. 


Breeding age of boars:  Boars can be bred at 7 months or older.  This is important so that you don’t have weak/small litters.


Same as the skinnies
Baldwin X Baldwin
When you breed two hairless Baldwins together, 100% of their
babies will all be Baldwins(with hair that falls out and become
totally hairless).

Baldwin X Baldwin Gene Carrier
There is a 50-75% or about half chance that the babies bred by a
Baldwin to a haired Baldwin gene carrier, will have hairless
Baldwin babies.  The rest will just be baldwin gene carriers. You
will know which ones are the true baldwins when their hair starts
falling off.  

Baldwin Gene Carrier  X Baldwin Gene Carrier
There is only a 25% chance that 1 or so baldwin babies will be
born in these litters.  You may have 1 or so carriers from this
breeding too.  

Baldwin X Regular haired breed guinea pig(not a gene
carrier of baldwin)

None of them will be a hairless baldwin.  There is a chance that
most of the babies will be baldwin gene carriers which can then be
bred back to the Baldwin.

Baldwin Gene Carrier X Regular haired breed guinea
pig(not a gene carrier of baldwin)

There is no chance a baldwin pup will be born from a Baldwin
gene Carrier bred to a regular haired guinea pig(not a gene

Baldwin X Skinny Pig(breeding not recommend)
None of the babies will be hairless like the Baldwins or Skinny
Pigs. They will all have hair and look like a regular haired guinea
pig, but 50% of the babies will carry either the gene for Baldwins
or Skinny Pigs and you won't know which ones they are.

All the Baldwins born in the litters will all have hair and look like a

regular haired guinea pig, and then their hair falls out until they
are completely bald.  You won't know which babies will be the true
Baldwin gene carriers until you breed them.
