What are the differences between standard and mini Dachshunds other than size?
According to the info we got from the AKC website (this is where my dog is registered) there are no differences other than size. I don't know if you have one, but several people in our area have bought Miniature Dachshunds that they found online, or at larger flea markets where pets are also sold, and theirs look very little like Dachshunds.
Be sure to check out the AKC website, as they have much good information about many breed types, and even have listings of reputable breeders.
I was fortunate in that when I got ready for mine, we have a very reputable breeder in our area. I did pay more for my pup than some of the others paid for theirs, but I got to see both parents, a few older siblings of my pup, and got a health record, and papers needed for registration.
AKC will say there are only two sizes of dachshunds; a mini which must be under 10 lbs and a full sized which can be up to 32 lbs. I personally own a 12 lbs dachshund and I as well as most people call them tweenies because they are too heavy to be miniatures but not quite full dachshund size. But appearance wise if breed properly they should look exactly alike. Full size ones chest seem larger but that is only due to size comparisons.
Go to www.dogbreedinfo.com and click on All Breeds, then find dachshunds. They say there are three varieties based on hair type and two sizes.
I read that there are 6 different sizes of dachshunds. You have the miniature, tweenie and standard. There is a dachshund size that is smaller then the miniature that weighs up to 5 pounds. I don't remember what the other sizes are called. I was at my vet with my miniature dachshund when 2 standard doxies walked out of one of the examination rooms. Those dogs were huge 30 pounds or more and not overweight at all. Tweenies are the size most people get and the ones you see the most. If you look up information about dachshunds you should see what all the sizes are called.
