We have a lovely 23 month old female golden....out of our previous four, three have succumbed to hemangiosarcoma (one with mast cell tumor before hemangiosarcoma) and one was born with bilateral, congenital renal (kidney) dysplasia.
our yellow lab that we adopted as a stray died secondary to highly aggressive poorly defined mesenchymal malignancy. CA is too abundant in all pure breeds but particularly in large canines.
like the saying goes, misery is optional and we repeatedly keep signing up 2-3 yrs after we've lost each one (euthanized at home, when their quality of life is poor) cause life without their presence is simply not tolerable. we have pondered an english with their lower CA incidence.... :(
