My 6 yr old rat terrier is drinking more water then usual.

She is always at the water bowl wanting water.She drinks and then she goes outside to potty and when she comes back in, she heads right for the water bowl. She is a little overweight, but I noticed that she might of lost some weight.She is an active dog.Its been about 2 weeks that she has been doing this.She does sometimes throw up a little, the water.
She also has nasal problems, could that be from being overweight? She is always snoring. Thank you.
