If you aint willing to keep them, dont breed them. Too many people breeding just because they know people that are looking for pups. If I dont want it at the time I'm not putting my dog through the stress of having and raising pups just because. I woul rather skip that heat and get her back in the woods
I got a bit off topic because of the other responses. Back to the topic, I have 2 Cat/ Walker crosses but I cant give you much info because I have not had them in the woods yet.
