Fat, thin or correct weight Dachshund?
The aim is to feed a quantity that allows your Dachshund to maintain the right weight for his lifestyle; neither under-weight, nor over-weight.
Your Dachshund is at an ideal weight if you can easily feel his ribs, but they are not visible. He should have an obvious waist behind the ribs, when viewed from above. There should be little abdominal fat and a slight tuck-up should be evident when he is viewed from the side.
Your Dachshund is not getting enough to eat if you can easily see his ribs, spine and pelvic bones. You will be unable to feel any fat on his bones, and will possibly notice some loss of muscle mass. He will have an obvious abdominal tuck-up, when viewed from the side. You should increase the size of his portions and maybe consider finding a food with a higher calorie level.
Your Dachshund is overweight if you cannot feel his ribs and can see fat over his back and the base of his tail. He will also have rolls of fat on his neck and over his shoulders. He will have no discernible waist behind the ribs, when viewed from above, and you will be able to see excessive abdominal fat or a distended underline, in profile. The risk of obesity increases with age and is more common in neutered animals, and there are associated risks of diabetes and osteoarthritis. The most obvious solution is to reduce the quantities your Dachshund eats (including titbits!), or move him onto a lower calorie food.
