peanut, I do brush Chloe's teeth; am not regimented about it like the doggie dentist wants, which of course is every day. I have brushed her teeth every day, but mostly I try to brush a few times per week, give or take. The older she gets, the more we both dislike it. My technique is probably more invasive than it needs to be. (cheap, hand powered, battery operated Oral B toothbrush b/c it has a small, round brush head + plenty of doggie toothpaste & brush by quadrants (6)). She gets a treat afterwards + I use the oral rinse after brushing as well which she can't stand. On her "off" days I just use the oral rinse (if I remember). As I said, I could do better. Doc didn't think she needed annual cleanings until she was around 3. I didn't brush her teeth when she was a pup; didn't really know. I thought WTH, are you kidding me?!...I didn't sign on for this!
Remember the dentist put one of those red tabs in her mouth (like they used to do w/your kids) to check spots I was missing. That really incensed me.
For awhile the vet prescribed Rx doggie dental food, until Chloe all of sudden decided she didn't like it anymore.
The best advice I got from the doggie dentist was: "If you can't bend it, don't give it to your dog." That was after the first root canal on upper molar from a pork chop bone. The 2nd root canal on the other side upper molar was after the doggie veggie dental chews they all sell (incl the dentist). After a refracture of one root canal clear under the gum line (I was warned extra care w/b needed to prevent bacteria from getting in there), I said to pull it. Had I paid for crowns on her two root canals, the refracture probably w/n have happened. I was just done w/dental emergencies. The rawhide with chlorhexidine took surface enamel from her canines (eye teeth), however my own dentist took a look & said the dentin wasn't exposed.
(yes, I took her w/me) Then she had one bad small back tooth that needed extracting. All of these problems started while she was entering her senior years @ 6 or 7 yrs.
Moral to the story is: daily brushing is best...probably w/a finger brush or doggie toothbrush, doggie toothpaste (people toothpaste toxic to them).
Dachsunds are known for bad teeth. They have a small jaw, but a mouthful
of crowded teeth which makes them prone to problems! Getting all the way 'back there' can be challenging. But for 14, she's in decent shape.
Don't know how this person got this pic. My experience is in a deep, dark cave that you need a crowbar to keep open. So that's my looong story to go along w/my looong doggie & I'm sticking to it.
However the short answer to your question is Yes.
Teeth brushing, grooming, bathing I find are opportunities to notice things.
Sounds like Fonzie is growing fast!
