My little 65 lb.choc. lb female is in her first season retrieving in cold water this year. Only a year old last of dec. Had preformed beautifully until water temps dropped extremely quick. First hunt after water temp dropped to just above freezing had a refusal to enter I,m positive was caused by water temp. Refusal was corrected and started working a lot on cold water retrieving drills during training sessions. Any thing I,m missing that I should be doing other than repeated training in cold water? Shes still a little balky on first entry but straightens up after initial entry.
