My 3yo Weimaraner dog weighed in at 43.7kg three weeks ago, he is very tall for his type but we've cut his good down. He has no treats (doesn't even know what to do if he's offered one!) and he weighed in today at 42.9. That's 800g in 3 weeks.
Is that reasonable for a large breed? The vet did day if he doesn't lose then we can look at low calorie food and/or thyroid test. I'm just not certain whether or not to go back so soon.
Any experience gratefully listened to.
