Honestly, I think all three of mine would be adoptable IF they were adopted out by the right organizations. However, I could see them being returned to rescue in a heartbeat!
Ilsa. Well, she's nearly 6 - still a good age, but getting older for a Doberman. She has a minor case of spay incontinence that requires cheap medication, but **** she's a pushy girl! She is vocal, so I could see her scaring her new owners with her happy growls, snarls, and barks.
Ronin... oh gosh, where to begin... well, I already know one family couldn't handle him, and it was a dog-savvy home to begin with. They ended up being scared of him, muzzled him 24/7 and crated him excessively. Sent him to a doggie bootcamp, and introduced him to abuse (he shows the hallmark signs of abuse - whether it was his handler, his trainers, or his owners... I don't know.). Ronin is a full-throttle, intense guy who is simply too much dog for 98% of the dog-owning population. He has male-dog aggression issues, separation anxiety (which is disappearing through consistency and training), and is sometimes a picky eater... who wants him?
Ada... very cute, cuddly, friendly, and jolly. She'd be scooped up in a heartbeat. She would be great anywhere, with anyone... but I could see someone returning her, with a frazzled look on their face as they brought her back - with a muttered, "I didnt know she bounced off the walls so much..." or, "I had no idea such a little dog could zoom around the room so fast that there's pawprintson the ceiling"... yep, she's a ball of energy!
