Well, it's not that simple.
This cough has been going on for a long time. I would call it chronic. There are several things that need to be checked though Elsa.
First - allergies do not typically cause a cough in dogs. And the rash may be completely unrelated to the cough.
Can you see videos?
I have collected a few different videos with different types of cough.
Take a look at these and let me know which you think it is more like, deal?
I have a good idea of what it might be, looking forward to hearing from you.
I would describe them like this:
With kennel cough, it is a series of hacking coughs, and then a gag at the end. Sometimes there is foXXXXX XXXXX stuff/phlegm that comes out. It goes kind of ACK ACK ACK ...GAAAAAAG!! Then a pause, then repeat.Kennel Cough 1Kennel Cough 2
With reverse sneeze, you notice that the pup is breathing in when he does it. It almost always sounds like, kind of an inward snorting type of laugh, and usually there is no gag at the end. It happens with excitement typically.Reverse Sneeze
The collapsed trachea happens when the pet is breating heavy. But, unlike reverse sneeze it happens after the inward breath, when the pet is breathing out. So they breathe in, the trachea collapses, and they COUGH out. You can hear the dog in this video breathing in before coughing out when it slows down a bit.Tracheal Collapse
The heart failure cough is usually a soft coughing, with a kind of locomotive breathing/panting. The pet usually does not look good. Their necks stretch out. They are anxious, their heads hang low.They are exhausted from trying to breathe so heavy.Heart FailureHeart Failure
