Both dogs run $80 to $150 a month, with first years of $1,200–2,200 and $1,100–2,300. As with several pairings on this site, the identical figures conceal completely different spending.
The Pit Bull's money goes on food and routine care, with essentially nothing on grooming. Its uncertainty is insurance, where bully-type breeds are frequently surcharged or excluded outright, and where an exclusion matters far more than a premium.
The Griffon's money goes on the head. A rough-coated dog needs stripping or clipping on a schedule. Eye problems are more likely and sometimes urgent. Airway assessment and, in some dogs, corrective surgery is a realistic possibility. Anaesthesia for routine dentals needs a practice set up for short-faced patients. And if syringomyelia is suspected, an MRI is not a cheap investigation.
That makes insuring early — before anything is diagnosed and excluded — more valuable for a Griffon than the low monthly figure suggests.
On the other side, it needs very little exercise at 2/5: twenty to thirty minutes of walking plus indoor play, which is why the 5/5 apartment rating is earned rather than generous. It travels easily, fits anywhere, and lives 12 to 15 years.
The Pit Bull needs an hour to ninety minutes of real activity and cannot be satisfied indoors.
So the decision comes down to two ordinary questions rather than anything about temperament. Can you supply an hour of daily exercise? And if not, are you prepared to take on a short-faced breed with the eye, airway and neurological questions that go with it — and to choose the moderate end of it rather than the extreme?
