Baby is really concerned about her injured pet and she wants it checked by the vet.
Accompany her to the vet doctor for an examination.
Clean the cute doggy from dirt and mud using a brush. Wipe its runny nose with tissue paper. This is not a good sign though as it might have caught a cold, so it needs to be treated for that as well as the body injuries. Take care of the wounds disinfecting them with antiseptic lotion and cotton pads.
