LOL That DNA test does not prove parentage and pedigree. As someone well versed in rescue, you should already know that. It will not matter for the purpose of an AKC GSD or Rottie club. You can only compete as a mixed breed or if the dog looks enough like a purebred, you may be able to get a PAL, purebred listing. Which, to be frank, you can do anyways as AKC clubs accept mixed dogs. If it's Schutzhund, again you can only enter as a mixed breed because there is no pedigree. You do you.
You're making an awful lot of assumptions. You're even bring kinda mean to be honest. I will do me because being true to ones self comes first.
1st) for someone who's been in rescue for over 20 years as I have I rescue dogs I don't buy them. Though I have many owner surrenders who come to me with papers many are also strays that do not.
2nd) I know diddily squat about AKC competitions because I rescue I don't buy and I don't compete. Rescuing for 20 years gives me little time to compete and I am also a single parent.
3rd) for once in my life I would like to pick my own dog as a puppy from a breeder. Yes buy a dog because after 20 years of rescuing I think I've earned a hall pass to do so.
I have gone through every heartache a German Shepherd can give you from DM to bad hips to megaesophagus. If I can prevent it I don't want to live through that ever again. I earned my stripes!
Jenna Mae was my first GS lost to hemangiosarcoma at 8yrs old. Ellie is my current picture she is now almost 10. Dutchess was my MegaE girl in my Album photos who also died after a good life but always remained special needs. Nala my Belgian Malinois though purbred and I have her papers she had 3 legs not quite ring material either. My son is in college now and my next dog will be one who also gives me a new hobby with training and possibly competing for fun.
To be honest with you I have no idea what a GS looks like at 6 weeks. I rescue adults. Not puppies. I have never been a puppy flipper type rescue. 🤷🏼♀️ but I did think this dog was perhaps a rott shep mix.
Regardless, I decided to rehome her. I took her in for a friend's rescue to socialize her with my other dogs. She is doing amazing well with housebreaking. But I decided today I do want a purebred GS that I pick out. I also am not sure I want to have multiple dogs anymore. I also have a pocket pal who is a 5lb Shih-tzu who can live easily another decade! Her father died at 18!
