Sudden death of our beloved 5yr old dog Lulu

On the 4th of January. Our beautiful girl crossed the rainbow Bridge unexpectedly. She had been well and when we put her outside yesterday morning was her usual happy bubbly girl. 2hrs later my husband went out to feed her and she was weak and very quiet and breathing funny.

Rushed her to the vet where she was monitored all day. Did x-rays, blood tests everything they could but she deteriorated as day went on. One of her x-rays showed lung not looking normal. They couldn't get her blood pressure up was super low. Her red blood cells kept spiking. It got harder for her to breathe even on breathing machine. She wouldn't of made the night we had to free her.

We are completely broken and devastated as she had just turned 5 in November and never expected to lose her so young. Vets still don't no actual cause so sending her to Massey for free post Mortem. So can get some closure. With this been so unexpected and all things tried to save her we now have a $1650 vet bill to pay,which not sure how to. So hoping if anyone can help us just a little at this horrible time to take financial strain off us. We would be so grateful. Rip Lulu taken to young from us.
