be very careful with the heat, don't hunt the dog more than an hour or so at a time, it doesn't take much to overheat them. my buddy's girlfriend took his springer walking last thursday evening, the dog went into seizures from heat exhaustion when they got him to the hospital his internal temp was 106 which caused his blood to rapidly thicken and basically boil, they were able to stabalize him to a controlled coma, sunday night his pancreas and liver quit and he died. the vet bill is over 4 grand not to mention the best upland dog i've personally ever seen, the cost of the dog, training, and 5 years of going everywhere with my buddy. duke was in fantastic shape too. if you saw all this happen it would answer your question, i now don't think its worth it for doves.
