Pug with allergies

Question
Hi, I have a 4 year old spayed female pug who is allergic to beef, lamb, pork, turkey, and corn.  She is not allergic to chicken and rice.  I have two questions.  First, what dog food brand would you recommend?  Second, she used to love chewing compressed rawhide bones, but since those bones are beef, she can no longer have them.  Do you know of any hard bones that she can chew on that are made from chicken or another animal like bison or kangaroo?  Do they make rawhide bones that are not from beef?  I'm looking for hard bones that will satisfy her chewing, not just soft moist treats.  I'd appreciate any advice that anyone can offer.  Thanks.

Answer
Hello, you can get Bision bones if you hunt around pet shops where I live there are only two shops with these bones, you get get chicken Jery its hard and chewy takes some time to chew, you can get rawhides made from pork but she is allergic, I reccomend Nyla bones the durable ones these are hard nylon but my boston terrier/jack russell terrier loves them my lab doenst care alot for them...and they are genrally hypo allergtic, I reccomend firstly the top of my list Blue buffalo Chicken and Rice formula or fish and potatoe formula(I use this with my two small dogs) and the chicken I use with my large dog
