Treats and chews
How do I introduce a new treat without upsetting my dog's stomach?

Short answer
Offering just a small piece of any new treat on the first occasion, then waiting a full day before trying it again or introducing a second new item, makes it far easier to spot a reaction and identify its cause. This one at a time approach is especially useful for dogs with a history of sensitive digestion.
Why a single small piece is the safest starting point
A small trial piece, roughly a quarter of what you might eventually give as a normal serving, lets you gauge a dog's reaction without risking a large volume reaction if the treat does not agree with the dog, and it still gives enough exposure to reveal most sensitivities within a day.
The value of spacing new introductions apart
Waiting at least 24 hours before introducing a second new treat, rather than trying several unfamiliar items in the same day or week, makes it possible to identify which specific product caused a reaction if one occurs, rather than facing a guessing game between multiple new foods.
What to watch for during the trial period
Stool consistency over the following 24 hours, any signs of itching or skin irritation that might suggest a mild allergic reaction, and general energy and appetite levels are the main things worth observing after a trial piece, since these cover both digestive and allergic response possibilities.
Key takeaways
- Offer just a small trial piece of any new treat on the first occasion.
- Wait at least 24 hours before introducing a second new treat to isolate any reaction.
- Watch stool consistency, skin reactions, and appetite over the following day.
- This one at a time approach is especially useful for dogs with sensitive digestion.
