First-time dog owner? Congrats! Take puppy classes. They are to train you, not so much your dog. Sams aren't the easiest for a first-time dog, but keep at it and keep learning.
I started brushing my IG's teeth as soon as I got them. 10 to 11 weeks old. They are pros now and my 4th IG actually gets excited to get her teeth brushed :)
You can train yours her to get her teeth brushed too. Try to keep training sessions short, not more than 5 minutes to start. However, you could do it several times a day if you want to make progress faster.
Be patient with her and yourself as you both learn, it's not going to happen immediately (it may take weeks of practicing every day), but if you keep practicing it will happen!
I recommend using Virbac CET Enzymatic Toothpaste Vanilla Mint. Poultry & Beef flavors make them want to chew and eat the paste which isn't what you want for brushing. The best small tooth brush is CET (single sided).
Use high value treats for training, something that she goes crazy for. Mine love and never get tired of Nashies Beef treats. Order soon if you're going to, they're rebranding and may be unavailable for awhile.
1. Start by swaddling her in your lap, upside down, give her lots of treats, during the process. Make it a positive experience by breaking the steps down before sticking things in her mouth.
When she's calm and happy upside down and swaddled in your lap, start getting her used to having your hands by her mouth, reward her with a treat for not pulling away, keep doing that until she's calm about it.
Next put your finger slightly in her mouth. You can use the sides where teeth don't grow (behind her canines) to pop her jaw open a little. Treat her to make it a positive experience. When she's calm about this move to the next step.
Start moving your finger around on her teeth, just the front at first, treating her frequently. Then move to the back as she gets more comfortable.
Once she's good with your finger, introduce the toothbrush by letting her smell it first. Then do the same steps as you did your finger (#3 & 4) with lots of treats and praise.
When she's good with the toothbrush, do #3 & 4 with Toothpaste on the toothbrush. Be sure to still give her treats as you do each part of her mouth. I usually break it up into 5 parts, top back right, bottom back right, front top & bottom, top back left, bottom back left. They have small molars in the very back of their mouth, be sure to brush those as well.
Once she's trained on it, it should take less than 5 minutes a day to brush her teeth. Make it part of your daily routine. I've just added it to my getting, "ready for bed" routine, which has worked well for me for 18+ years and 4 IGs :) None of mine have ever lost teeth, had gum infections, or bad breath even my 1st IG that died at 17.
I've had good results over the past 17+ years and 4 IGs using C.E.T. toothbrushes with Virbac CET Enzymatic Toothpaste(Vanilla Mint). If you get poultry or beef it encourages them to try to eat/chew which you don't want for brushing their teeth well. Even my 17 year old had her all teeth, no cavities, bad breath and never needed a professional cleaning.
IGs can have a genetic issue, Familial Enamel Hypoplasia (FEH). You can get her tested for FEH and 2other common IG genetic issues at UC Davis. The process is easy, I've done it with 2 of my dogs so far. It also looks like Embark's purebred test kit includes FEH if you're interested in getting info about 210 genetic health risks instead of just 3. I've done both, Embark is more consumer facing, UC Davis is more for breeders. They're both easy to do but there are more features with Embark for a similar price.
Amazon has a vanilla mint one
i brush my cats teeth, sometimes daily but sometimes i get busy and skip a couple of days. we use CET toothpaste and i think it probably tastes good for them. i started with my finger and moved up to a 360 toothbrush which i think she kinda hates but tolerates. i might switch toothbrushes soon, to something even smaller. my vet was super impressed by her teeth, she's going on 5 and hasn't needed anything done to them. by this age many cats have to be put under to get teeth cleanings.
i would not feed dental food. feeding kibble in general just isn't worth it, health wise. pick a product from the Veterinary Oral Health Council's approved product list. anything else is not proven and therefore questionable. the one i picked out was Purina Dentalife treats.
hope this helps!
We use this toothpaste that the dogs LOVE, I mean so much so they try to eat the tooth brush. It's called "CET Enzymatic Toothpaste Poultry"
