my dog has problems breathing when he wakes up in the morning then he usualluy coughs in the morning he is a min pin
Coughing can be caused by kennel cough, canine influenza, bronchitis, asthma, heart or lung problem, etc. Frequently the cough will show up at night or in the early morning. It may just be a touch of bronchitis, in which case your vet will prescribe an antibiotic.
I do think you will need to schedule an appointment soon with the Vet so that it is caught early before it can develop into a more serious condition.
Hope this helps.
