i got my lab puppy at 8 weeks in december 2020. after i brought her home, I played fetch with her with tennis balls and pheasant wings for several weeks. at 4 months, I took her our to some hay fields that had knee to waist high grass and worked her on a lead, using pen raised quail tethered to "pigeon poles" to introduce her to live birds in controlled setting. I would let her lead the way, but I could keep her from catching the bird before it took flight, or when it reached the end of the tether.
at 5 months, I took her out to the grass fields and planted a few live birds while she was back in the truck, and then I turned her loose and we wandered the fields until she found them. if she got too far out, I woul dchange direction and she would come running back to stay relativelty close. when the tame quail flushed, she gave chase. i shot over her with a 28 ga. and she showed no noticeable reaction to the gunfire. the pen raised birds only flew 20-30 yards and she would fetch the, back to me.
she's been on 6 trips with me so far, half with just us, and half where she has been exposed to a couple pointing labs and GSPs. After a few days with the more polished pointers, i can tell she is more deliberate before flushing a bird she detects in the taller grass.
at 4 years old, she is a proven house dog, and proabably wouldn't score any points at any field trials. but, she seems to always be happy and eager for a good time for 2-3 weeks a year strolling the fields in SD, and she usually brings back any birds that are knocked out of the air.
