Thommo has put on some weight - a combination of the sore feet, winter, and my being away. So he's going back onto Chris Zink's pumpkin diet.
"Take 1/3 of your dog's regular dinner away and replace it with 2/3 canned pumpkin. It only has 40 calories per cup so you can really increase it quiet a bit and still not be adding much. If after a week or two of weighing your dog on the same day at the same time, you don't begin to see a weight loss....increase the pumpkin and the lower the kibble until you start to see a steady loss at 1-2 pounds a week. Just like people, any more per week is unhealthy. Keep the dog on this level until the desired weight is reached then slowly decrease the pumpkin until you are left with the regular dinner. At this point you may need to increase your kibble some, but by weighing every week...it's readily apparent if you dog is still losing or starting to creep up again."
