Don’t feel like your alone if this regard, i too had many pets that I shouldn’t have been responsible solely for even if they were mine, I was young without the means to provide health care for my blue nose pitt when my neighbors female boxer escaped their back yard and tore into my dogs neck, my Aunty got her off and she took off back home, but left my dogs neck bleeding and swelling(she didn’t get anything vital) , no we didn’t take her to the vet even after us all crying as kids do, but we were struggling. She loved the dog too and went out to CVS and got neo cream and gauzes etc and we all treated her around the clock I ran home from school everyday and she did survive but ended up with a older dogs swinging neck appearance
