please help!!!!

[summer]

please help,
i noticed blood on the carpet and kitchen today.
i checked out his butt and it doesn't look like anything is wrong and he still has regular bowel movements(don't know if i spelled that right).
i think he is coughing it up.
it just started today. he also feels warmer than usual. we just moved to canada from texas so do u think that maybe he just has a cold?
there are no warms in it, i checked for that, but i'm worried sick!
he is about 2 years old and a mini-dachshund.
what should i do? i don't want to take him to the vet unless i have to.
please help me.
