I am thrilled with Doc’s life vest. I think he actually likes it too, despite the look on his face right now. He’s not hesitating at all anymore to head into deep water after his tennis ball. Now that he’s had a layoff, I have to be careful that he doesn’t overdo it. He grunts a lot when he’s swimming or climbing up the steep boat ramp. He doesn’t seem to be tired so much as straining. I’ve got to try to judge how much stress he is under so he builds up strength in his back legs without making him sore.
