I know nobody reads this for my sage life advice, but you're going to get it anyway. Now that I have grey hairs literally growing out of places on my ears that no hair should ever grow, I think this entitles me to dish some out.
So my pearl of wisdom is thus: If you decide to adopt or otherwise procure a puppy - Brush their teeth from a very young age. Basically, just get them used to it. Seriously your window of opportunity is VERY NARROW here. For my sweet sweet man Levi, I started trimming his nails as soon as I took him home. Cradled him like the little jellybean that he is, and just got to work on those dainty mitts and now we're totally cool with the whole operation.
When it came to brushing though - I sort of magically thought that dogs were just exempt from this petty concern. I figure any species that can eat the poo of both itself as well as from soiled nappies while somehow not dying would not have to bother with actually cleaning said filth from their teeth. Also, I tried those finger toothbrushes and it just didn't work. He has a very small mouth and I have very fat fingers. I think I really just left it too late, but it might not be too late for you!
This is just a long way to say that in his eighth year of life, poor poor Levi had a total of TWENTY teeth pulled the other day and it just breaks my heart. I didn't even think he had that many, but lo and behold, dogs have 43 teeth.
I'm assured that despite the incredible agony that this caused him that he will now be much more comfortable in general not having rotten teeth in his mouth. If he plays his cards right, he may even develop an incredibly cute feature where his tongue sticks out all the time on the side which despite the fact that it came as the result of a horrific dental procedure, will give myself and anyone who looks and him incredible joy. I'll keep you posted.
Speaking of incredible joy... you know how this goes right? Go on, get out of here...
