Looks like Evo is adapting well to the new environs, as is Springer. Is she a dark brindle? Looks like it from the pics...always interesting to add a new member to the pack. Matrix has been good for Tango and Rider, and he's a sweet boy...knew a sucker when he saw him
Renea and I have had at least one Boxer since we've been married. We've had 5 now since Evo came to us. Sassy Girl and Drake were our first Boxers. Both were brindle. I'm not an expert by any stretch of the imagination, but I've been told the term "reverse brindle" is a misnomer. Evo's breeder termed her a reverse brindle. Although she is very dark, like all Boxers, besides the whites, her base color is fawn. Her brindling (stripes) is so tight that it appears her base color is black with fawn stripes, thus leading one to term her as reverse brindle. She's simply a brindle Boxer.
Be all that mumbojumbo as it may, she's a terrific little Girl. Springer adores her. Annie Bea scoffed at first, but is quite protective of her. She's much older, and can't really keep up with Evo. Evo is FAST. It's so much fun to watch Springer and Evo play. They're a joy to have.
