Willy working for his treats

Willy weighed about 20 lbs (9 kg) when I adopted him in 2020 and in 2022 he’s now down to about 14 lbs (6.3 kg). He’s 10 years old, now, and I don’t know that he has ever exercised much. Despite his large size, he’s unable to leap onto a dining table, much less a kitchen counter, so I’m coming up with exercises for him to build his strength and skill. He might not ever be able to leap, but he has improved at this simple exercise (although he’s often more focused on rubbing his chin on corners).
