Hello I have a beautiful golden named Oliver. He has a lot of energy and i have been taking him to this field next door where there is a lot of dust and dead plants. I take him there to throw the ball and have him do a lot of excersize. I noticed shortly after that he starting coughing a lot like he had a hair ball stuck in his throat. I gave him a lot of water and didn't think much of it. I continued taking him there for three days and he continued to cough. He is acting completely normal except for the coughing. it is not all day its super random that he coughs during the day. I am extremely worried and hope it is allergies!!!!!! I just lost his father to eating a rubber chew toy that got stuck in his small intestince. I am still very emotional of his loss and would not be able to handle another dog dying!!! please someone give me an opinion!
