Another weird issue? Their skulls are too small for their brains. This causes a condition called Syringomyelia (SM)—think of it like a too-tight shoe for your brain. It makes them scratch at invisible fleas or cry when you pick them up. About 25% of Cavaliers have it, but most show no signs. Just don’t let them jump off beds after age 5.

But here’s the silver lining: these dogs are bulletproof in personality. They’re the golden retrievers of the toy breed world—friendly with everyone, including cats, toddlers, and Grumpy Next Door. You could drop a bomb and they’d ask for a belly rub. Their emotional lifespan? Eternal joy.
How to Squeeze Every Year Out of Them
Want your Cavalier to hit the 14-year mark? First, feed them like a king. No, not from the table. Things like grapes, onions, and chocolate are poison to their tiny systems. Stick to high-quality kibble and avoid fillers like corn. Their hearts need omega-3s (fish oil is a godsend).
Second, exercise with purpose. They don’t need a marathon—two 20-minute walks a day are perfect. But please, no jogging in summer heat. Their flat-ish faces make them overheat fast. Think “leisurely sniffing tour,” not “Couch to 5K.”
Third, vet visits twice a year. Starting at age 4, get an annual echocardiogram. It’s like a mechanic check for their heart. Catching MVD early means meds that can add 2-3 years to their life. That’s extra snuggles. Worth it.
