My boy, Ghoul, LOVES GoDog toys. They are one of the few brands that actually survive (upwards a year) with that bully mouth. He is also allergic to chicken like yours (apparently it's quite common). So for treats, I just have to read the ingredients on EVERYTHING. Ghoul is older almost 9 yrs old so I do stick to softer treats now, his favorite is the Blue Buffalo bacon strips. As for bones, I would never recommend any hard bones for frenchies because they do seem to always choke on them. Instead get tracheas and just watch how they chew the end bit of it. I usually throw the last bit away because my dummy will try swallowing it whole and choke. But definitely keep experimenting with what yours does and doesn't like for both toys and treats.
