My 12 year old Cairn Terrier is coughing/ gagging.

Hello, my 4 year old Staffordshire Terrier all of a sudden has become sick and we don’t know what is going on. He has suddenly started to cough which ends with him gagging. He doesn’t want to eat and just lays around sleeping. Occasionally, he will get the shivers. He has still been drinking water and will still go out to use the bathroom. I just hate seeing my little ball of energy looking so tired and miserable. I’m wondering if it’s kennel cough that has progressed or something of the sort. Anyone have any opinions or ideas of what it could be or what I can do to help him? We have very limited income right now.

My Serbian Husky is throwing up constantly. Today she has at least throwed up 20 times. I just recently got her 3 days ago. She’s 5 years old. Her stomach cringes and she will stop gagging then a puddle of slimy clear liquid with a little foam like substance will come out. After she eats she throws it up and you can see the food and it looks like it hasn’t been chewed up. When it does this, it’s ALOT. It’s really white and foamy. I have no clue what it is and I’m freaking out!

My dog just a few months ago had surgery for cancer she seemed to be doing OK and recently she started moaning a lot and when she gags it sounds like a lot of air coming out ?

So I thought he was making himself throw up to eat again. Because he doesn’t really cry or seem in pain. But I switched his food to see if that would help. But lately he’s been throwing up way more, and it’s mostly just clear and a small amount of white foam, and sometimes some food mixed in. He still doesn’t seem in pain and doesn’t cry. Sometimes he gags to get it out, other times he will literally just be walking and a small amount will come out. He’s also been drinking quite a bit of water lately. And urinating quite a bit when he goes outside. But other than these symptoms, he seems completely fine.
