Sounds like a young buck wanting to make some money. I dont agree with selling pups for anymore than £100. At the end of the day, a pup will only be worth what you make it.
After you buy the pup, you gotta have its innocs which are about £40.
Lad's i know sell pups for £30-£40, enough to pay for the pups food and treatment for bitch before breeding. And a tiny bit profit.
If my bitch comes anygood i will be breeding from her, when she's 2year old at least, and the pups will be going for no more than £50 apiece.
I know a bloke who sells dogs regular, one word desribes him
