Be aware, however, that pumpkin is an anti diarrheal, so the dog may have
trouble passing its stool. It's a great short term remedy for loose stools
in both people and dogs.
A good way to lose weight (both people and the dog!) is to take it biking.
I put the dogs on a 'better' kibble and worked them *** the bikes and
they both muscled right up (walking wasn't enough for my younger boy- too
slow for any progress). Now my guy looks much better in the ring, and I can
keep right up with him.
If it's a young, old or physically impaired dog, try swimming as it's better
for joints (no impact). Caloric reduction alone isn't the answer as the
body will eat away at the muscles before moving onto fat stores. Exercise
is the only thing that will keep this from happening.
