Hi and thank you so much for this query. He can eat just anything. The feared infections with dog bites are rabies, tetanus and a bacterial infection because of the open wound. However, with vaccination and wound care, this would be very very minimal. Also, I will like to know if he received and antibiotic(amoxicillin+clavulanic acid) to cover for germs present in the dogs mouth. I hope this helps. I wish you well. Feel free to ask for more information and clarifications if need be. Thank you so much for using our services, we very much appreciate this.
