I Have A Seven-Week Old Miniature Daschund. How Often Should I Feed Him?

Puppies, especially small breed dogs, need to be fed 3-4 times daily.  I would feed your Dachshund 4 times a day initially.  It is important to feed a high quality diet specifically for puppies.  The total calorie requirement can be divided over the four feedings.  Diets can vary on the calorie content--I use the bags as a guideline then adjust for individual puppy needs. 
Keep in mind that your miniature Dachshund is a lot smaller than even a human baby.  For these little guys even 8-10 kibbles can be a full meal. 
Between 4-6 months you can start feeding your dog twice daily and continue this frequency for life.
Weigh your puppy weekly to make sure it is continuing to gain weight.  Also and even more importantly monitor his body condition.  You should be able to feel his ribs easily but not see them (except the last 1-2 ribs that end the rib cage in a Dachshund).  His spine and hip bones should be easily palpated but should not jut out.  He should have an hour glass figure looking at him for the top and a tummy tuck from the side.
When you see your veterinarian for your puppies vaccination series consult with them about his weight, body condition, diet, and feeding schedule.
Good Luck!

This is a growing puppy and should be fed around three times a day with water 24/7! Buy puppy dog food though because it helps the pup grow. When it gets older though, around two years, top buying puppy food, or they will start gaining weight!

I have always kept puppies well fed...although I started teaching them the sit and wait when feeding...then when they are done eating they usually have to go out, good time to start house breaking, by habit...anyway I have found over the last 20 years that pedigree seems to be the best food...there is not much if any soy meal in that food...here is how I used to feed( my dogs were between $500 and $ 2,000 each and extremely healthy and happy/active)  morning : Pedigree dry food mixed with a little cottage cheese(about 1 teaspoon full) 1 teaspoon of canned(like the stew w/beef...chicken, etc.)   early afternoon :same without the cottage cheese...late afternoon :just a little (maybe 1/4 cup) canned food...early evening, before 8 pm...just a little dry food...make sure you walk your dog after each feeding, will help make a habit of going out after food and easier to house break...always make sure your puppy has all the freshwater he can drink and remember...puppies don't have much control of bodily functions...walk them often...just like a child...everything they do is a learned thing, and you are the teacher...be gentle but firm...

I have a two year old Daschund. How often should I feed him?

After feeding all that I have decided that I will probably feed my six week old puppy four times a day since she seems to want food all the time. I plan to feed her at 7am,11am,3pm, and 7 pm or at least try to get near those times.

I have an 8/9 week old mini daschund also and I feed her 3 times a day

Puppies should be fed 2-3 times a day since this is the time that they grow quite fast. You should buy premium grade dog food so that your puppy will have all the nutrition that he needs. You might also want to invest in a good pet food container so that the dog food won't go stale. Read more about it here: pet food storage
