Loki is fat. She's deep-chested, so it gives more of an illusion of trimness. But she doesn't do much these days -- she's 8 and basically retired from any sports -- so she's got a little weight on her. I always kept her light in her younger days. In spring she'll probably tone up a bit as we all come out of our caves. I think she could lose 2-3 pounds and not miss it, but I also don't monitor her weight, just her health. She's not so far gone as to be unhealthy, so I don't worry about it much.
Here is Loki a bit more fit a few years ago:
And here's an old pic of Loki at her fittest point, about 2-3 years old. She got a lotta lotta work at that time, and was eating quite a bit of raw instead of straight kibble.
I put a lot of work into Terra during spring-summer so she looks good for the shows, and yes, she's flexing in these pics. Right now she has some more weight on her for winter, but the tone is still there. I talk about this from time to time with a dog friend who is also a fitness buff himself. The body remembers. Seems like when you condition once, its easier to get dogs into that shape the next time. I'm hoping that next year she will have an even easier time of it.
I'm still learning about getting a dog into really, really lean shape. Its hard to get those results spot-on unless you've got a dog that's really genetically blessed.
