At most we would pay $300, and that is for a wolfhound rescue. Maybe we would pay more for a livestock guardian one day, but I am not there yet. Of course I don't have a pasture of pricey fiber animals either.
I am a rescue person and I am not crazy about puppies. I mean, I love puppies, but if I wanted another baby, I would have another human one.
Any other dog we would pay under $100 to get. Morgan, our current dog, was a shelter rescue. She was at a no kill shelter and had been there 2 YEARS!! We went in looking for a black lab and when all the candidates were just too crazy for us we asked for the best most patient family dog in the house. The rescue worker said, I have two really great dogs, but you aren't gonna like it, they are both pitbulls. We asked which one had been there longer and she brought us a white and tan pit bull mix. We met and were hooked. She has the best disposition, is fantastic with our kids and cat, and is the most well behaved dog I have ever had in my life. And conveniently she was free. We adopted her in September which is national adopt a pet month so they waived her $50 fee. She was already obedience trained, fixed, and up to date with shots. All the freebees were nice but I would have paid $1000 for her if I had known how special she is. She is terrible with the ducks chasing and wanting to eat them, her prey drive is pretty high, but we are working on it and she is making serious progress.
I think a dog is worth whatever you are willing to pay. If you wanna spend $2000 on the perfect fit dog for you and you think it is worth it, to you, it totally is.
