Dental hygiene

I had to go to the vet on Thursday - something to do with a 'booster' whatever that is, and a health check. The appointment was early and I think Jenny arranged that specially because, when we got there, there were no cats, no animals of any kind, in fact, and we went straight in to see the vet. She poked and prodded me and said I was a nice dog. I was doing a lot of sniffing around the floor and Jenny said I  had probably picked up the scent of cats.
"He likes cats, he just couldn't eat a whole one," she said and the vet said, "Ah yes, he has Border terrier in him," as if that explained everything. I don't know why Jenny assumes I couldn't eat a whole one, she's never given me the chance to try!
Anyway, I bore my injection very stoically (Bet you didn't think I would know a word like that!) and then the vet looked at my teeth and said that they could do with cleaning, so she suggested either Dentastix (yum, yum) or a dog toothbrush or special wipes.
Later, Jenny went shopping and came back with Dentastix and some dental wipes.
You're really going to put your fingers in his mouth?" Keith asked incredulously (See, another big word).
Well, so far, she's given me Dentastix.
The pot of wipes is still sitting on the dining room table...
