Hi, and welcome to EBN to you and Boss Hogg. At 6 weeks he's still very young and his tummy could be sensitive, plus he should be on a puppy formula to ensure he's getting the proper vitamins, minerals and nutrients he needs for growing. I wouldn't worry about giving him treats yet, but if you are potty training him or other training, and you want to reward him, you can just give him a piece or two of his own kibble. I usually carry a little sandwich baggy with a handful of their kibble to give as treats. I would wait until he's a little older to introduce store bought treats, maybe at 10 weeks old. You still want to be careful on which ones to buy, many store bought pet treats and cookies are full of fillers and chemicals that aren't good for dogs. We use Fruitables, Wellness soft chews, and Benny Bully's liver snaps for occasional treats. Watch the labels and choose treats with limited and natural ingredients. We also give our guys fresh fruits like bananas, cut up apples, strawberries, blueberries, and watermelon, and plain unsweetened yogurt on the morning kibble, plus we give them cooked carrots, broccoli, cauliflower and green beans on the evening kibble. If you decide to give him any of these toppers, introduce one at a time and for one week before introducing a new one, that way you will know if he doesn't tolerate or shows allergic reactions to anyone them, and you will know which one caused it.
