I have a 14 year old Jack Russell. He has Epilepsy and is on Phenobarbital and Potassium. And has been on this for years. Lately over the past 6 months, he wakes up every night between 2-3:30 am. We give him a small bit of food, he goes into his bed in the living room, will not come back into his cage in the bedroom. The barking and whinning he's doing to get his way are awful. Any recommendations??? By the way he eats very, very well. So this extra food is piling the pounds on.
