The breed average (which can be found on the KC website) is 7.4% for a coefficient inbreeding, so yes 14% is way too high. HOWEVER, don't be wedded to that. 14 is much too high. But mine has a score of 10% - but his hip and elbow scores are superb, so I was prepared to compromise.
The KC website also shows a sliding scale of what is 'good' and 'bad' on hip/elbow scores (they should have both done as a minimum). You can also have a look at the bitches/sires estimated breeding values for potential pups.
https://www.southerngoldenretriever.com/health1/#breedstandard - the link explains the breed standard including scores etc. But PP is correct, an elbow score of 2 is not great.
A good breeder should also have their bitches heart and eyes tested (at least in my opinion)
In terms of things to be aware of, OP...and specifically goldens (I've copied some of the below from another thread earlier). I'm sure you're aware, but I cannot flag enough the below:
- Golden's (and mongrels bred from them) are HIGH energy. They need a good 1-2hours a day. Any less than that is cruel. That is in cold and warm weather (in summer you have to be up early). If you cannot provide this, they will destroy your house and your sanity...
- Their coats need consistent maintenance (2-3 times grooming a week)
- They are mouthy and when they are puppies (up to 18 months) their mouthing can, on occasion, border on aggressive as they do not know their own strength (they're big puppies - mine was 12KG at 12 weeks)
- They are NOT good with young children. They stay puppy like (as larger breeds do) for up to 2 years and routinely knock young children over. Once they are adults, they can be. But up until then, they are not - and they do need constant supervision (as any dog does).
- They are expensive both in terms of purchasing (reputably - a pedigree golden is anywhere between £2-£3K, and non-reputably) and in terms of maintenance (grooming, toys, flea treatment, insurance, wormer, feeding)
- They come with a variety of health issues (cancer, dysplasia) all of which are expensive to treat (£10s of thousands over a lifetime in a bad case) and ongoing issues.
That being said, despite all those 'cons' - I wouldn't be without one. My Golden is 15 months and he is already the best dog I have ever had. But it takes a lot of time/energy. They truly are amongst the worst puppies I have EVER encountered (and I've had spaniels and GSDs...both of which are v. high maintenance) and you have to go into it with your eyes open.
I'd also speak to several breeders before you choose one to go with. Be prepared to view a couple of litters (please don't just blindly go with the first litter you see). Getting the right dog takes time and patience.
