Theory:

     Not wanting to keep César and his companions apart, the staff let the dogs inside after giving the him the medication he needed. They even offered some food to César. “Believe me, he ate some and saved a bit to give the dogs later." Mamprim recalled.

     An hour later, César left the hospital with the four dogs trailing behind, happily wagging their tails.

     “I do not know what his life is like, or why he’s on the street, but I admire the respect and love he has for his little friends.” Mamprim concluded. “Seeing them like this, waiting at the door, just shows how much they are well cared for and loved.

     Even though César has little material possessions and likely has no kin to turn to, he is never alone because he has his warm and loving companions.
Explanation:
  
The medical staff did not want to keep César and his friends apart, so they let the dogs inside after finishing his treatment. They gave some food to César. Again, he ate some food, and he saved little food for his dogs, as recalled by Mamprim.
 
After an hour, César left the hospital with his friends following him, happily wagging their tails.
 
Mamprim finally said that she did not know what his life was like, or why he was on the streets, but she admired the respect and love that he had for his little friends. Even though he did not have food, he tried to save food for the poor stray dogs. The scene of the dogs that stood waiting there at the door just showed the amount of care and love César had given them.
 
César did not have any money or wealth, nor does he have any relations to go back to. But, he will never be alone in his life, because he has his kind and loving companions.
