Look, I appreciate your willingness to help people and keep on top of this forum (seriously, few have the time these days and you do a great job helping people) but statements like you made here just make you look like an ass.
Me? Why do I bother? Because I *always* end up with the chins. And people right now are spreading some terrible stupid notions. You know what happened last month? Someone told somebody that it was OK to only feed hay for a week. IT KILLED THEIR BABY.
You can NOT only feed hay to a 10 week old, they will die. Hay does not have enough nutrients in it. She died a horrible death after seizing for an entire day.
So I told myself I would become more active in the forums again because this is the information they find on google. We need to help these chins, not kill them. I'm tired of taking in chins in late stage organ failure or with deformities from hay-rich, starch rich and sugar rich diets. These are young chins and getting younger, many under five years old suffering gross health issues.
I've taken in hundreds of surrenders and been involved in a few legit forced-seizure rescues. I have touched tens of thousands of chins moving, selling and buying herds. I have seen some weird-ass crap and just when I think I've seen the worst it can get someone one ups that.
So, after 21 years I can tell you;
Hay does not contribute to tooth wear, using the teeth does. Wether they are used on wood, pellets, roughage or cat food, the action of chewing wears the teeth. That old pair I got in that had been fed cat food all their lives had great teeth.
Genetics determine fur strength which determines matting. The grease ball cat food eaters above had never seen a dust bath and had no mats. 80% of the chins I take in have no mats, more than half of those haven't seen a dust bath in months and some never due to the owner's allergies or lack of knowledge. It is actually pretty shocking how many people just don't dust their chins. That said, I get some in where the owner dusts near daily and they have mats. It's genetic. Heck, I bred the violet in the video above that got mats - and that is why I sold him and quit breeding that line.
Bathing - Depending on the type of fur your chins have you may need to dust daily or only weekly. Tiffany's Chinchillas runs Shoots lines and has to dust daily. Mine only get it weekly unless I am a few weeks before a show. Mine look great, you can walk into my barn and even though I grab them and snuggle quite a few times during the day they still look soft and plush. It is a stronger, shorter, plusher coat type.
If you are dusting daily keep an eye on their ears, it can dry out the ears and feet. If those feel fine you are not dusting too much. You might have better mileage using a higher quality dust like
chilldust - you don't need to use as much, it isn't as dusty and it does a great job. It is the go-to for shows now. I can't stand the feel of the blue beauty (blue sparkle) but the chill dust leaves them feeling very soft and is not as dusty.
Hopefully this helps someone. If anyone has questions on diet, or would like to see research on diet there are some great articles I posted on this forum back in 2003? And I can also send you some newer ones. Just email me at my website below or message me. Heck, if you are desperate, call. My website has my phone number on it.
