Toby needs help

Toby is my 10 month old mini dachshund, he is the love of my life.. Friday night Toby had multiple severe seizures that nearly took his life. He has been in and out of an animal hospital since that night. He is on multiple medications to stop ongoing seizures and he has also been having multiple scans. Specialists have narrowed it down to being a liver shunt but due to his size and him being so young this is a extremely serious condition and he will be needing surgery. Toby was also born with only one kidney which is another reason why his condition is so serious. My family & I are needing help with the funds to properly help Toby. Our pet insurance company is trying to refuse to help us so we are desperate. Please, even the tiniest donation could go a long way. I am asking from the bottom of my heart to please help. It will mean the absolute world to me. Please share the go fund me link. Thank you all so much in advance
