I paid £950 for a working cocker female two years ago. Excellent bloodline, KC papers etc. Wasn’t looking for another dog but the litter came up from two relatives breeding their dogs, female is a farm dog and the male was my uncles working gun dog. Unfortunately he passed away not too long ago and it was a real shame. Brilliant dog right to the end but his head went and that was it sadly. Used to work with the female every day when I was on the farm and ended up putting myself down for one. Initially they were north of £1300 or something like that but the bubble seemed to burst during the pregnancy.
After I got her, two of my neighbours rushed out and bought males in the same colour. One asked if I was interested in breeding but I said no thanks. If I remember correctly, they ended up paying over a grand for him.
