Need answers from vet assitants, or vets or people who are very smart in doggy info?

ok, so my dog got sick over a week ago, probably 2 weeks ago, she got bloated, and wouldn't eat her dog food, called the vet, they said to give her gerber baby food flavor chicken or turkey, did that, she lost weight, so they told me to make her chicken and rice in water, i did that, she got way better, and started gaining her weight again, but she develop a cough, but she would only cough, when i would go out to feed her, that's the time where she would cough, and cough, but, then she got better, today, it was sunday, went outside, and found over 20 big puddles of blood all over her enclosure, i called every vet i know in my city, seeing as it was sunday they were all closed, and none had a emergency number to call, ok, so i cleaned her enclosure, cleaned her blanket, gave her new water, and put down food for her, she hasn't cough again, and hasn't cough up blood ever since 2pm on sunday, which its now sunday after 11pm, she ate, she didn't want to eat her dry dog food, so i gave her, her can dog food for healthy digestion, cause she has constant diarrhea, she already saw the vet for that, they said that she needed the can dog food for healthy digestion which help, she got better, the amount of blood in her enclosure, it should of knock her off her paws, but she was up and acting like normal, still has a bit of a cough, also, i found a big branch in her enclosure, thinking she might of swallowed a small piece of it, and it got caught in her throat, she vomited blood and threw up the stick, don't know, anyone out there know anything about this

2weeks ago, she was bloated, wouldn't eat her dog food didn't poop for 3days

vet said to put her on gerber baby food chicken or turkey flavor,

fed her that for 4days, then put her on chicken and rice in water

fed her that for about 7days, i gradually introduce her normal dog food back

she is now eating a can of dog food for healthy digestion mix in with dry dog food,

and went outside, today and found her enclosure full of blood puddles everywhere

check her mouth, it was nice and pink and the blood did come from her, she had blood fizzing out of her mouth cause she was still coughing

like i said, i know 3 different vets, called all 3 today when i found her enclosure full of blood, the vet offices were closed, and there was no emergency number left on there answering machine to call

will call the vets tomorrow, to make an appointment for one of them to come out to my house to check her, draw some blood, take it back to there office, and do some test

just want to know from other people, what the h*ll could of cause this
