My dog keeps removing his sutures after being neutered. Shadow was neutered on Tuesday morning and during the night he managed to remove the sutures at home. He went back to the vet on Wednesday to have more sutures put in and about 20 minutes after picking him up from the vet's office, I noticed he didn't have any sutures again. He had not licked once while in my care during those 20 minutes because his nose was stuck out the car window. This means he removed them while still at the vet's office. Who is responsible for payment of today's procedure? I understood paying when it was my negligence and purchased an e-collar to put on him but I never even got the chance yesterday. I'm trying to know what common practice is and know what to expect this afternoon when/if I'm handed a bill. Thank you for your opinion.
