How old is Ziggy?
How much does he weigh and how much is he eating of how many kcals/day?
My Puff is a "mutant" Lab, one of the rare 10% that self-regulates her food intake.
Over the last year or so, I'd gotten lax in the amount of food per meal I gave her AND rather than a scant 1 cup 2X/day, I'd been giving her generous cups at those times.
I was concerned because lately she was skipping some of her suppers, not eating them at all.
Last week, when we went to KSU's CollVetMed Tchng Hospl, she weighed 65 lbs. instead of her normal 62.
I began decreasing the food given/meal back to our former "scant" measurements.
Puff is now eating supper regularly.
AND, her poops are smaller and MUCH firmer.
Puff apparently knows very well what she needs.
It's humbling to have a dog smarter than you -- but kind of nice when you both can form a team to make a mutual decision.
