Boxer Puppy appears too skinny

Question
Greetings !
I just bought a boxer, he is 2 months old and he appears to be very skinny... his ribs are visible !
He plays a lot and eats normally as well. I feed him 4-6 times in a day. I was really concerned about his weight so i got him dewormed yesterday !
he weighs 4.5 kg (10 pounds) and is only 1.5 - 2 months old

Answer
If you had him dewormed-- you were at your vet's office?

Did the vet say anything about his weight and ribs showing?

I can't tell you much without knowing exactly what you feed him, and to be sure he lives INSIDE a climate controlled house; not hot and not cold, etc.

I would need more information. However, Boxers genetics from parents can range from smaller one that will not weight normal weight and height with a smaller bone structure to larger ones (adults 60-65-70 lbs) with large frames.

I need more information about his daily feeding and life, and parents if you know about them.
