Hi! I won't go into much depth on this but is there are those out there who have experience w/ their dogs/pups on this condition I would really appreciate your comments. My 10 mo old BLF and one of her sisters is believed to have a depth perception problem which shows up in marked retrieves of 150 yds and less. Problem 1st started on 75 yd retrieves and has progressed to longer retrieves. Result is the sister pups continuously hunt short of the mark. My pro trainer who is highly recognized and myself are perplexed. Vet opthamologist checked and no eye structure or disease problems. Sire/grandsire(NAFC champs and lineage never has had this condition.) We're thinking it might just be a mental/physical developmental problem but we're still at a loss. My plan is to develop my pup for derby field trials but if we don't overcome this condition I end up w/ a good gun dog but she will never be able to compete at the trial level.
