Yep...pricey...5-6k for a $900 dog. But Enzo is part of the family and its coming on 3 yrs now. He's still got some lumps and skin tags...but it beats the alternative...(tho I'm jonsin' hard for another German Shorthair Pointer)...Don't tell Enzo that!
As far as advice...you need to go with your pocketbook and your heart. How old is your Dane? As I recall they don't get many years...correct?
I'm glad I did it tho...the 1st pic above was the 1st time I took him out and he found that quail that the other one had given up on it...right then I knew it was worth it. I still take them out 1-2x a year for canned phesants since they'll hold longer than wild birds. Best of luck!
