I would also recommend a good standard smooth.
I'm very
and wary when I read about breeders who mate X with Z and hope to get a Dalmation sow or A with B to get a lemon agouti sow with the intention of keeping the sow to breed.
What about the ones that don't make the 'grade' or are a boar............well read Gumtree and you'll see countless "Baby boar guinea pigs for sale. lots of colours, email for details" and a photo of 8 piglets.
My older sows were ex breeders , unfortunately they were not bred well and their piglets (who I didn't see, they were weaned away when I got them) had abnormalities and some died.
My Himmy has ruby eyes and is very sun sensitive , but as long as she has shade she'll graze when the light is duller.
Long haired are hard work
Abbys have little chisled short noses (very cute but can have eye and nose problems)
Rex and Teddy are huuuge
and in our house very allergenic to DD.
As long as the parents are old enough to breed , the sow doesn't have too many litters or too old in breeding, they are handled and the boars leave the Mum/Sisters before they are fertile ( can be as early as 4 weeks) then your pigs should be good.
We champion Rescue Piggies , all mine are characters, mad as several boxes of frogs, judgey as only a Rescue can be (our boar is Entitled ) and we love them.
