Here is another nice video from Standing Stone Kennels and something you are likely to have to deal with if you do a lot of back country hiking, and/or upland bird hunting like us. Last year we spent over eighty three days afield hunting, and easily as many just out hiking. We had two Q-Pine incidents, just in 2018. Ethan does a pretty good job here and I'd like to add a couple of pointers to help you get your dog through this. First if it's a fairly minor incident like one one captured in the video, by all means, do your best to calm the dog and get those quills out. I keep a pair of spring loaded leatherman pliers on me additionally my hunting vest has a pair of hemostats on board just for the purpose of grabbing quills. You really cannot pull quills with your fingers, but you can use your teeth! I only advocate the use of your teeth if you are either crazy, or you dog is ultra-calm. If you have a helper, like in this video, have them help calm the dog - it will feed off of the anxiety - so breath deep and chill. Even more importantly, have your buddy do their best to keep quill impacted skin puller tight. As you remove quills the skin will be able to slide against the dogs body normally, this is the high-risk time when broken quills can and will pull through and go under the skin - this is a trip to the veterinarian. Ethan does a really nice job giving his dog an good exam, which is just perfect. If your dog has really been hammered by Ol' Porky - disregard all of this, and get him (or her) the the vet as sedation is most likely going to be necessary.
I'm just a guy suffering with an infatuation with gundogs since childhood. Forty some odd years later this is what you get.
