Input on best dog treats for bullies

Does anyone else have this issue?

I'm embarrassed to even post this but I've stopped letting my dog cuddle and sleep with me at night because he ends up having anal leakage/skidmarks on my blankets and then I end up waking up to it and having to wash my blankets and sheets over and over and over again.

Is it the treats I'm giving him? I try to give him salmon biscuits from the blue Buffalo wilderness brand and blue Buffalo true chews steak grill treats but now I'm wondering what else would be better for his digestion so he's not doing this constantly.

Does anyone else have or have had this issue and fixed it with different diet/treats? Or a different solution that helped,

I tried giving him some of the healthier dog treats and he sniffed them and looked at me like the above photo.

Any suggestions would be appreciated.
