What If My Dog Is Too Skinny But He Eats A Lot?

Some dogs especially large breeds tend to be thin because they grow at a fast rate. As long as he or she is not vomiting or having diarrhea its ok. I currently own a lab, a rott, and a mastiff. All three dogs looked malnourished as puppies but were eating more than the recommended amount. The vet can check their nutrition levels if you are very concerned.

You have not mentioned age and weight of your puppy and either your dog is maintaining his weight or losing. If he is maintaining his weight and eating normally and not having any other signs of illness then he is normal. If your dog is eating good but losing weight then it is not good. Following are some conditions that can cause this.

1. Absorptive disorders of the gastrointestinal tract like inflammatory bowel disease
2. Problems with pancreas
3. Intestinal cancer
4. Diabetes
5. Cushing's syndrome
6. Insulinomas
7. Liver tumors

So, you should take your dog to vet and discuss with him.

I have a maltese and have the same problem. He eats like a cow but only weighs 4lbs. But he is very active. I mean he will run around the house and when I let him outside he has so much energy, he will walk 100 miles. So it all depends on how active your dog is as well. And P.S. When I just got him he had worms too and I got him dewormed and now he's actually up a pond and a half. He was really skinny when I just got him.

He may be very active, or he may have worms. Try a good commercial wormer, if that doesn't clear up the problem, it's time to visit the vet.

If your Rottie is eating normally and is not gaining weight, then there is a Medical Problem somewhere! You need to take your dog to the vet and find out what the problem is and get it treated. Only a vet can help your dog on this!

He may have worms. You should take you dog to the vet to get him wormed. It may also be the quality of food you are feeding. Try a more natural foo with no fillers
