I also had that problem before with my dog. But he only coughs if he drinks water too fast. I went to a vet to see if he has any serious problems. Good thing it was only because he drinks too fast. Right now, I make sure that he only drinks his water slowly.
I am the lead content curator for Coops And Cages as well as a couple of other pet related blogs.
My passion for animals is only matched by my love for 'attempting' to play the guitar.
I have a mini dachshund who is going thru back problems herself. She started walking around in a circle and hen just not want to walk at all. I took her to the vet and she told me that she had a disc that had a calcium deposit on it and that was causing her the pain. Sassy was given pain mess along with an anti inflammatory medicine. She has started to show improvements in just a day and a half, but no jumping, no stairs, and lots of rest. She has to go back and the vet is going to do acupuncture on her. I hope that it works.
I have a little breed dog she does this when drinking water it is due to going down the wrong whole check with your vet if overly concern. I had test done she was drinking too fast. I used a drinking bowl that prevents her drinking the water too quickly cured the problem. Hope this helps x
