Q. So my spaniel turned 14 this past January, he is about 30 lbs, he was always very active, running chasing birds, but he has become very lethargic

A. For older pets that have become lethargic, the first thing I would want to check is their heart. Especially in cocker spaniels as they are predisposed to certain heart valve issues with age. Your vet can do a heart auscultation (listen) for any heart murmurs or arrhythmia's. If that checks out fine, then a senior panel bloodwork is recommended to make sure all the organs are functioning properly. This will give us the most information on if everything is ok or if we need to implement some treatments for your pet now to prolong your pet's lifespan and treat disease early.
