The con of having a mini Sn is that if one of the mini Sn has a standard gene in it it can cause the pups to be too large inside her & could kill her.

MY friend had one across from my old place & they had a standard too.

They got her in heat & talked to the vet about it. they had to keep he caged or locked in a bedroom just incase the neighbours dog got to her. The neighbours always let their JRT loose (hes attacked all dogs on that street) & hes not fixed. & the JRT was larger then Clair.

The breeder they got her from said she was a really good sized & healthy dog & said she would have been a great breeder, but after my friend learned about the birth problem she got Clair fixed ASAP. She said Clair was her baby & didn't want rick her life for stupid puppies.

Her standard SN male was fixed before they got him. he belonged to her aunt who died & she got Buddy. Buddy was 10 when she got him.. poor old fellow. his pee pee was broken.
