Help Maxx Recover from Multiple Emergency Surgeries

Hi, my name is Sydney, my dog Maxx had to have surgery because he ate a peach pit. He did well the first day after surgery, but the second day, he declined again. He stopped eating and was throwing up, drooling and burping. I took him back to the emergency vet, and they told me they think something was missed, and suspected he still had something stuck. So he went under for his second surgery. He did okay the next day, but then declined again, and was back to vomiting, drooling, and burping. He stayed in the hospital for three days, and on the third day they called me and told me he still isn’t better. They told me that they suspected he had cancer. They recommended that I keep him there and say my goodbyes if he doesn’t start feeling better by the evening. I went to get a second opinion, and they told me that it’s very unlikely to be cancer. The doctor said he likely has an overload of medications in his system causing his digestive tract to stop working. He is at home now, and seems to be feeling slightly better. I unfortunately had to pay for the surgery twice. I could really use some help and support through this potential negligence case. My dog is sick. Any little bit will help. Thank you all.
