Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!
Is this new or chronic in nature?
What color is the discharge from the nose?
chronic and usually clear
Ok - this is not uncommon in this breed,.
Based on the conformation of their nose.
If severe and bothersome - Often in these cases we consider treatments such as steroids (Prednisone - LINK HERE) or antihistamines such as Benadryl (LINK HERE).
If the discharge was yellow, white, or green - the concern would be more for an infection -and antibiotics used.
Common antibiotics to consider in these cases includes:- Clavamox (LINK HERE)- Azithromycin (LINK HERE)
Other considerations would be humidification. Twice daily you can either use a children's / baby's humidifier for 10-15 minutes twice daily, or using the steam from a hot shower you can attempt to humidify the air that your dog breathes.
being constant it becomes annoying cause its every minute or less, especially licking of the tongue
This is why If severe and bothersome - Often in these cases we consider treatments such as steroids (Prednisone - LINK HERE) or antihistamines such as Benadryl (LINK HERE).
Unfortunately - this is a breed related issue, not specific to your dog - seen with Brachycephaly and a the pushed in nose.
this problem has been since birth and has not changed. the agitation and loud panting is the same, the dog doesnt know how to relax or to accept gentle loving . is this all related to the shih tzu?
Yes - this is common with this breed.
the prednisone link sends a 404 file not found error So to answer all the questions is ther e anything that can help to reduce or lessen the symptoms of the breed?
That is an updated link
Those are the common recommendations used here.
thanks will try benadryl to see if that helps...
