Owners of aging dogs who want joint-formula ingredients and an NAD precursor in one daily chew, and who like that the NMN works out cheaper per milligram than the capsule alternative.
Your dog already takes a glucosamine supplement and you do not want to double it, your dog reacts to shellfish or fish, or you want NMN on its own without eight other actives attached.
