Other than getting a kibble for large breeds, the biggest kibble I’ve come across while finding food for my pugs is Core Reduced Fat and Core Original. It’s sort of triangular last time I used it and would consider it medium sized. I thought it was a little large for the smaller pugs. Although kibble is hard to digest so getting a larger kibble would make digestion more difficult. The smaller surface area and diameter of kibble the easier it is to breakdown. (Although size of kibble is not the only factor in good digestion). I’ve read here that some large breed owners dogs did better with smaller kibble versus large kibble. Specifically someone’s large dog did better digestion-wise on EVO Small Bites (which he accidentally bought) vs the regular size EVO. Same flavor of kibble, just purchased the wrong size. That being said you have the option of adding a probiotic/digestive enzyme to help with digestion if you go with a larger kibble. Most dogs don’t chew so a large kibble might be a choking hazard. If your dog likes to play with food how about putting the small kibble into a treat ball (like an IQ ball or Kong) where he has to work to get it out.
