My doberman is 1 and half month old, since I got him he is not eating at all, I give him forcefully. And every time he is having loose motion. Sometimes he is active but most of the time he sleeps, and I find him depressed sometimes.
He took deworming 5 days back, again he's has to take it after 2 days. He is little tiny. What can it be? Help!

Have you taken him into the vet to see if he has any medical conditions?

The vet said he has worms, and he gave him deworming and he has to take dewormin again after 2 days

Poor puppy, I would call the vet and see if he has any ideas on how to get him to eat anything until he's had his second deworming.

Anyway I'm going to the vet tmrw. And its surprising rite now he is eating very well by himself first time... am so so so happy

Good! Good for him!
