Our then 11 year old Cav (Norah) developed heart disease a couple of months after being put out for dental care. This also seems to be the case for many of her litter mates and half brothers and sisters.
Now her younger half brother (now 10) needs dental, some teeth to be removed, and we are scared this will trigger heart disease in him.
Thoughts? is dental disease painful? how would he indicate being in pain?
