@TheEveningReport happy to help! The problem with FPS is it could literally be anything. And even if the breeder catches it in time, you can't always solve what's wrong with the puppy as it's often multiple things. It's particularly hard if it's actually the puppy that is the 'problem' (i.e. genetic) - sometimes it's things like the dam not having enough milk and the breeder not catching it in time, or it being too cold or too hot. So it is a tricky one and doesn't necessarily mean the breeder is at fault at all.
FWIW, 3 is a good age for a litter (assuming it's the dogs first) as almost all breeds have hit physical and emotional maturity by then.
Where the breeder sleeps is important to me simply because all the good breeders I know sleep by the whelping box for at least the first 4-5 weeks, if not longer. That's to ensure the puppies always have someone on hand should they need anything and also to keep an eye on the dam (not only for her own health, which is incredibly important but also to protect the puppies if she 'snaps' - stressed dam's can kill their puppies, so supervision is always important). Even so, it doesn't mean we always catch things but it does give us better odds of catching it in time.
On children, I should have clarified! I don't sell to families with children under 10 (or with frequent 'young' visitors) for two reasons;
- I also do rescuing for my breed (Golden Retrievers) and about 95% of the dogs we get in are being re-homed because of bites on children. Almost always provoked (child not being supervised, dog being tormented and eventually 'snapping') but it's not a position I would want to put my puppies in.
- I've also raised children around puppies (I had two under 5 at one point + a litter) and even when the litter had gone...it was bloody awful trying to manage two young children and a puppy. And when DDs were 7 and 10 and I had a litter, it was a nightmare - even knowing as much as they did about dogs, and being carefully around them, I'd constantly find them about to do stupid things. My youngest just entered secondary, and it's night and day in terms of how they reacted around the last litter about 8 months ago.
I would stress that good breeders do sell to people with young children (although I do question the sensibility of children younger than 8ish for particular breeds such as particularly working dogs or gun dogs). With me it's just personal preference, which is why the facebook group don't like me as they think I'm unreasonable in my stringent criteria - which to some I probably am, but I absolutely stand by my choices.
So my overall advice would be to gently (and I say gently as if the breeder is a good 'un and genuinely loves her dogs, she'll be devastated by what happened) ask what happened and if she knows what caused it and go from there. Let me know how it goes! This will sound so patronising, but I do love it when people genuinely want to 'get it right' with buying a puppy and make sure it's the right fit from the right breeder.
Sorry that turned into quite an essay...
