Welcome to the site, @codee! and bless you for adopting your 7yo bully! A couple things come to mind: you can fill a Kong toy with some peanut butter and have Martini lick the pb off. You can get some cream cheese and shape into balls or logs and give these as a treat. What i've mentioned are rather "messy" treats so when i give these to my boys, i usually do so in their crate. Soft meats can also be used as treats...like boiled chicken cut up into small pieces. Hopefully others will be able to give you some suggestions!
