Jas,
I hunt a small Lab retriever for upland. She's a 2yr old about 50lbs and just hyper. I feed Pro Plan dry food currently. Which canned Purina did you use?

On my hunts, I've just been giving more of the Pro Plan. But, I'm always interested in improving. I hunted 6-7 hrs with my dog on Saturday and noticed she was running out of gas after about 5 hrs.

I've had various recommendations on feeding before, during and after hunting. Near as I can deduce from all the recommendations from hunters to vets, is: one; you don't want their digestive track so full during hunting that a twisted gut is likely, two; you need to supplement their burnt energy in order to sustain performance. I've been feeding a little heavy the night before a huntday/after a huntday, feeding very light in the morning at least 4 hrs or more before hunting and giving a small handful of Pro Plan dry halfway thru the hunting day, followed by light another small handful after hunting while still in the field, then later, her dinner. Seems to be working, but I haven't deviated too much from this.
