Can you please describe his symptoms for me?
When did he start having the problem?
Ok thank you.
Can you tell me how much he weighs and then we can make a plan?
Ok thank you
There is also an over the counter product for hairballs called "laxatone." It helps prevent and resolve hairballs. You can purchase it at most petstores or online. It comes in multiple flavors. I imagine he is not too picky. Try 3-4 tablespoons every other day or once a day.
To help settle his stomach, you can give him 75 mg of zantac (ranitidine) every 8 hours by mouth.
I would feed him a bland diet of plain chicken and white rice until he is feeling better.
I just thought I should mention kennel cough because it sounds like hairballs but there is not hair. There is a link below.
