A Sick Dog

We got a kitten from the SPCA and I think he’s sick, now my dog is showing signs of being sick.?

First it started with the cat. He was fine the first night we brought him home, then we started to notice he was sneezing alot and his eyes were running a great deal. Well, I have a long haired chihihua at home and she’s always done that reverse sneeze thing. I always just called it honking til I googled her symptoms. Anyways, I’ve started to notice that she is sneezing alot, along with the "reverse sneeze" more than usual.The past two days the "reverse sneeze" has been really bad. She can’t even get up and walk w/o it hitting her. And if she regular sneezes, its immediately followed by a "honk" Also, I just noticed her nose is a little runny. I am going to call the vet tomorrow. But I am worried about her. Could it just be a cold???
So, a cat can give a dog this infection?

Sinus/ upper respiratory infection. Very common in pound animals, and contagious. the good news is that it is easy to cure. take them both to the vets for antibiotics.
