Dog Obesity?

 I started my pup on baby carrots from his first day and he still sees those as an awesome treat

I have no experience with the ones you mentioned

 I use banana chips and Tootsie goes nuts for them.

I have not used those particular treats.

I regularly use green beans as treats.  I also use a portion of the dog's food as training rewards.

I'm not a big fan of gimmick-y "low calorie" or "weight reduction" treats.  It is easier, imo, to adjust the dog's meals around the amount of treats that you give throughout the day, than it is to worry with buying special treats.

I monitor the dogs reguarly and adjust the volume in the dinner bowl (they are fed twice per day).  I use really high quality treats for training that can be broken into small pieces and tiny bits of human food.  The only time I have had to do more is when there is a medical condition (hypothryroidism). Many folks with obeses dogs free feed. The amounts on most dog foods are a bit over what the dogs actually need in many cases.   When they see food in the bowl at human meal times, they assume the dogs are hungry and entice with high calorie.  Dog learns to wait them out and gorge....

Its all about timing and measurement, n

 I only use organic or homemade treats for the pups, you may want to try this recipe... I never have peppers on hand so I just increase the celery and carrots or sub green beans and the puppers go nuts!
