Support Gunner's Life-Saving Treatment

Hey everyone, my name is Nikki and I am asking anyone who is willing and able to help me and my family keep our fur baby alive during this Christmas season. His name is Gunner and about 4 days ago he starting showing concerning symptoms of vomiting his food up anytime he ate and acting lethargic. Through the next 3 days, he progressively got worse to where he wouldn't eat at all and was vomiting bile and what we believe to be digestive blood. By day 3, he would lay down and not want move with a lost gaze in his eyes(still showing zero interest in food/not eating). We were able to(with help from family) get him in for x rays and blood work. The vet found nothing wrong in the blood work and a clean report on his organs(heart, lungs, kidney and liver). They discovered a large amount of gas trapped and concerning images with his intestines. Without an ultrasound(which our vet does not perform) we are unable to tell if, what they believe the issue to be, there is a blockage in his intestines. They injected him with fluids for dehydration and another injection of medicine to help with nausea and apatite hoping this with home care would help him get back to eating and force the blockage out. We are seeing no improvements after 12 hours(which the doctor said is very concerning). We are graciously and humbly asking whoever is able to help us raise the money for an overnight stay, ultrasound(which the vet highly recommended) and most likely a surgery to remove the blockage(foreign object or mass on intestines) . We understand this is the worst time of year for a lot of people to help financially but we are desperate to save our baby who we've already been informed has a lot of life left if this issue gets fixed. To lose our amazing dog right before Christmas due to lack of funds would be devastating for our family and children especially. Thank you with all our families hearts ahead of time to those who are able to help.p
