The evidence would suggest a 20 to 30% infection risk with a penetrating dog bite . So usually 3 days antibiotics. So , maybe not penetrating. They probably thought , ''do we trust grumpy, who lets face it , thinks our Goldy is an overpriced , pampered pooch , or get the dog checked ''. Maybe they remember old ''Bluey'' getting a .22 hollow point for his 10th birthday. Peace of mind , priceless.
ps I was joking about the doggy spa and the pedicure. not the vet visit.
