Baby tyson

For those of you who no me no that I absolutely adore my puppy tyson, as do my children. But last night we had the worst night I have ever had in my life, tysons had a serious accident he was running along on a field (on a lead) but then he noticed another dog (off a lead) and tyson ran, and I let go of his lead, it all happened so fast and I didn't mean to let go, but I did. I tried to chase him but I have stood on his lead, tyson came to a sudden halt and because I was running so fast and I've accidently tripped and landed on his tiny head, he's so so small. So as this happened I heard a huge yelp, then nothing. He was lying on the floor lifeless with blood covering him head to toe, it was coming out of his eyes, nose, mouth and he was just so floppy. We were in the middle of a field, we had no car as we took him on a walk, luckily we got this lovely couple to pull over to take me to the nearest emergancy vets (I am registered with pets at home but he wouldn't of made it that far) so I took him a vets on Wennington Road in Southport. On the way tyson was fighting for every breath, going in and out of consciousness, bleeding an uncontrollable amount whilst I just held him and cried, I thought he was already gone but he kept fighting, he was  choking on blood and sick, his tongue was white with shock and lack of oxygen. I got him the vets and rushed him inside and they took him straight away, giving him oxygen, painkillers, antibiotics and a fluid drip. Which was £200 but I could only get hold of £125 on the spot. Tyson stabilised, whilst I waited at home doing nothing but crying and trying to explain to my children what happened on that park (they seen everything, they where screaming devistated) I can't stop seeing his little face, we miss him so so much and so do my children. We got a call at around 7pm that there was no out of hours vet to care for tyson last night and they where not happy to leave him, so they told me to transport him to ribble hospital in Penwortham, without any oxygen tyson was at serious risk of passing in the car, but he didn't, he was fighting so so hard. The hospital called me this morning and told me that tyson had made it through the night with only 1 hour of oxygen and he yet again is still fighting to be here. The bill being £300 up to now which I didn't mind, as getting him put to sleep wasn't an option whilst he was fighting so hard to stay, so after this bill they have done a scan aswell as a few more painkillers and anti biotics, they could not see any brakes or fractures on the scan which points to tysons injury being neurological, which means he needs transferring to another hospital, which is a minimum of £3000 and with his other treatments is just unaffordable for me, please don't get me wrong, I work full time and have a decent job but I still couldn't afford that, with 2 young children and a house to run, I am finding it near enough impossible to raise the money right now, tysons dad is poorly and been laid of work due to covid so I haven't got any other option but to do this. Tyson is insured but because I took out a brand new policy 12 days ago they refuse to help, I've contacted pdsa (not in catchment area) and other charity's but none are in a position to help me right now. I want my boy back and I will do whatever it takes, I love him like I love my own children and I feel physically sick this has happened, but now I need to do anything to get him better, there is no other option, he is fighting to be back with us so the least I can do is help him in anyway possible, any dog owners out there who have been through anything like this you will understand the pain I'm feeling right now, I feel sick and the pain is un bearable, I miss him so much and he doesn't deserve to die, if it was a human we wouldn't just put them to sleep so why would we do that to an innocent animal, I'm not giving up on him I can't give up on him, and I am begging you all to come together as a community and help me raise the funds to save tyson even if everyone could do £1 each that's still more then I have now towards the bill to save his life
