Thank you for getting back to me. I suspect your puppy is not too thin. A dog should have a "waist" when you look down from above. If there isn't, she is overweight. Feel her sides. You should be easily able to feel the ribs. If all the ribs are very visible, or the backbone protrudes, the dog is underweight. These two methods are better than using weight alone to determine if a dog is at a good weight. Dachshunds are very prone to becoming overweight and that leads to serious back problems. they are better off being a tiny bit underweight.
The amounts of food recommended on dog food bags are meant to sell more food, not keep dogs healthy. very few dogs need as much as what the bags say. Feeding a dog properly has to be very individualized because every dog is different. One 38 lb. dog might need 2 cups of food to maintain that weight, while a second dog of the same weight could gain weight on that much food, and need only a half cup. It will also vary with different brands. A dog may need 2 cups of Royal Canin to maintain its weight, but if changed to a different brand, it may need 1 cup, or 3 cups. The best way to keep your dog at the desired weight is to weigh her at least every other week, check her body shape regularly, and adjust her food as needed.
I'm not sure which controversy you're referring to about dry vs. canned. If it's about dry keeping the teeth cleaned, that has been disproven. I have had various dogs on an identical canned diet. One needs the teeth cleaned twice a year, even with brushing and chew toys. Another one, at age 13, has sparkling white teeth with nothing done at all. Heredity has a lot to do with plaque accumulation. Of course, brushing is a good idea no matter what. If canned food helps your dog eat enough to maintain good weight, there is certainly no reason not to use it. On the following reputable site, you can find more complete information on choosing a dog food and all aspects of feeding a dog. http://www.dogaware.com/dogfeeding.html
