underweight rottweiler

Question
hi i have a 3 year old male rottweiler and he is very much underweight i have had him neutered but it has not helped at all. He is also so freindly with everything untill he has food, then he is very aggressive. if you can think of anything i can try i would be most greatfull. thank you.

Answer
Hi Michelle,  Have you had his thyroid checked or had him checked for diabetes?  Both of these problems are common in Rottweilers.  I would have some blood work done to check and see if there is some underlying problem going on that you can't physically see except for the symptoms of leanness.

Hope this helps,

Dawn
