Thank you for your patience. There are a number of possible causes for Foxx's intermittent coughing and choking, and while this could be related to her allergies, it could also be a sign of anything from a primary respiratory issue like asthma, an infectious issue like kennel cough, a foreign body, tracheal collapse, or even an internal organ issue. The fact she is urinating less frequently likely relates to the amount she is drinking, so do continue to encourage your girl to have good drinks of fresh water.
Because there are a range of possible causes for her symptoms, you will definitely need to continue to keep a close eye on her. If she hasn't improved at all by the morning, then you are definitely safest to get her seen by your local vet tomorrow morning if possible. For now however, please keep an eye on her mucus membranes, capillary refill time and respiratory rate tonight as follows (do be careful that your girl doesn't try to bite you):
Mucus membranes - flip her lip and look at the color of her gums. They should maintain a nice salmon pink color. Get her to the emergency Vet if they appear white or very pale pink, or if they are a dark deep red color.
Capillary Refill time - this measures blood perfusion and test this by putting your thumb on her gum to apply pressure. After you release your thumb you will see the gum blanch. Capillary refill time is the amount of time it takes (in seconds) for the gum to return to a healthy pink color from the blanched white color. If 2 seconds or less don't worry - if it is taking significantly more time, again - off to the emergency Vet.
Respiratory Rate - if she seems to be panting or breathing rapidly throughout the night, this is a sign of shock and or pain and a signal for a trip to the emergency Vet.
