Man oh man! That letter scared the belittles out of me!
One well informed letter, but I would have to send back your deposit if were me. Unless a yorkie is several months old its really pretty impossible to guarantee weight. You can sure do your darnest to estimate and it can be right on it but sometimes they do their own inherited thing.....
My guarantee only covers life threatening conditions such as congential heart disease or liver shunt, so I couldnt agree to replacing a puppy due to LP, although I would absolutely want to know the extent of it so in the future the knowledge may be used improved in our dogs.
All breeds carry certain established inherited problems and you can try until dooms day to get rid of them all, but genes are genes....you cant erase the past, you can only try to minmize it.
Look at Hitler he tried to produce the master race, look what happened to him. I certainly wouldnt call him or his people the cream of the crop. But the ones who survived it were!
SO much for my off color sense of humor! Plz dont take offense Im only having fun, but there is some truth in it to me regarding breeding.
