Two things you can try: Coconut oil. It's antiviral, antifungal, and antibacterial. Used to be in the food supply but was removed because of a poorly-executed but media-viral study about 20 years ago.
I've been using it with my family and pets for about 6-7 years now, and it works very well. Honey. Pedes now say it works better for coughs in young children than OTC cough syrups.
Another one of those things that's safe for dogs.
We had one that was about 2 years old when she turned up stray--we figure she was dumped because she was sick (she had distemper, bronchitis, and pneumonia and coughed like that for a long time). I would take the animal back to be further evaluated--by now the severety or frequency from a cold alone should have diminished (it's not like the animal would cough hard for 2 weeks then just stop, it would gradually improve). A cough can also associated with other problems, though the cough when they have heartworms, for example, wouldn't necessarily be as croupy sounding cough like you seem to be describing.
Here's a remark from one web site that covers it: >>>>The most notable symptom of heartworm in dogs is coughing. Coughing, as it is, is a common symptom Dogs with heartworm tend to suffer from a soft, dry cough. This condition is due to the parasites which have found their way towards the lungs.
The lungs, including the veins leading to it, get irritated with heartworms as they multiply in number in and around the area. Prevention truly is the best (and least expensive) approach to many pet illnesses today. Good luck to you and the pooch on solving this one!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
