Please help McKenzie!!

Please help with McKenzies vet Bill's! She is currently receiving a blood transfusion and we are not exactly sure what's going on. She is Currently at Broadview Animal Clinic in Aurora, Co. Donations can be made directly to them Broadview Animal Clinic [phone redacted] shes there under her moms name Helen Bibb (if you do call in please comment that you called in so we know!) or donate through here! Her leg started swelling a few days ago and we have had her to 3 different vets between Texas and Colorado. My dad is a Truck Driver and this all started out of no where on the road. One vet said it was a tic disease the other said she was poisoned. Regardless, she is now having a blood transfusion and NEEDS further testing! Please help shes my dads road dog/child/bestest friend! Even a dollar helps and if you can't we understand but we would appreciate a share! Thank you!
