We had a pup born with CP 2 years ago, which wasn't picked up until he was 6 weeks old. He was smaller than the rest of the litter, so I took over hand rearing him. To cut a long story short, we found him a wonderful family, who already had another cocker, he was fine until he reached around 18 months old, then started suffering nose bleeds, this was down to infection in his nasal cavities.
He was taken to Langford, where his new owners paid to have the CP repaired. We were also told that it is common for there to be a secondary problem associated with CP and this is cataracts. We took the pup to Thornbury, where he was checked out and yes he does have cataracts, but only out the outside of the nucleous, so whatever sight he was born with, probably won't get any worse and he will cope.
He's just coming up 2 years old now and a picture of health.
This was him at a week old, next to his sibling:
This is him now fighting fit
No more infections, no more 'snotty nose' just a happy healthy cocker!
