I'm getting my pup in the near future and signed up for a subscription service for Pupbox. Apparently they send different 4-5 different types toys and treats each month of the puppy life for the extent of your membership. I signed up for a year. I wanted to work on training right away so I wanted treats on hand. Should I be exposing my pup to so many different commercial treats? Is it safer on digestion/allergies and health overall to just stick with 1 low calorie training treat instead of having a bunch of different types of rotating treats. I could be overthinking it. I had a dog in the past that suffered horribly with allergies so now I'm wondering about this. My question is does anyone on the forum have good experiences using this subscription service or could answer the question above?
