I found a mixed pup and her mother is full dachshund, the puppy this morning was fine, but now she is out of it, her nose is very hot and runny (clear) her body seems very warm, and she yelps and screams when she moves at times or just yelps when just sitting, I have no idea what could be wrong as I haven't had a puppy since I was like 6 yrs old.
Is there anything I can do for her now until she is taken to the vet as that costs a lot of money and I'm gonna do the best I can...She was fine this morning playing and acting alert..
I'm afraid in a situation like this the only thing you can do is get her to a veterinarian right away.
It's absolutely impossible to tell what's wrong otherwise and it could be something serious that needs immediate treatment.
Yes, veterinary care is expensive, but when a pet is sick there isn't any other option if you want them to have a good chance of recovery. Some vets will work with you and allow you to set up a payment plan. Also, as you don't know what's wrong it may not be as expensive as you think it will be.
The first (and only) thing to do is contact your vet and get her examined asap. I wish you lots of luck and hope this little one makes a full recovery.
