Iris Obstruction Surgery

Im basically on my last option here, my world , best friend, love of my life has an obstruction in her stomach that cannot be passed over time. She needs an emergency surgery the longer I wait the worse it gets. We have spent weeks staying up all night because of her abdominal pain. After multiple vet visits and 500$ +  spent we went from strep throat to gastrointestinal blockage. If any one out there who can relate to the love some of us can feel for our pets and understand my pain of not being able to help her please :( I will forver be greatful with whatever you can help me with. The money will be spent only on her whole process she needs to go through , from radiographies/ xrays , medication , surgery itself and after surgery treatments. The sooner I can get this going the better , her symptoms have gotten worse drooling and not wanting to eat and it only hurts my sould not being able to take her place instead just so that I wont have to watch my baby suffer this much. All I want is for her to be her happy self again munching on her favorite food and walking 10 k steps every day at the park and excited to go for walks. Waking up early to start her day with me and play time with our family. For whoever reads this and donates what they can I will forver be greatful and right now my only hopes is having my fingers crossed that it wont be too late I am not ready to say goodbye to my best friend/ soul mate .Thank you <3
