Bought a pup of renowned Patteradle breeder 6-7 years ago that had to be put to sleep around that age due to a heart defect, had two separate vet reports sent to the man direct and he refused to give my money back for the dog. Full of promises when I bought the pup, if it doesn’t work bla, bla, bla, fetch it back ill give your money back in full. Learnt the hard way there, but there you go that’s life.
