My dog, yorkie, was imported from abroad a year ago. She was diagnosed with rhinitis (bacteria or virus in her nose) and put on antibiotics a week before she came to New Zealand. There was a positive progress in the beginning but it turned worse when the dog was released from quarantine in Auckland.
At first, it was a running nose only. We went to a very good vet in the city, however, she couldn't decide on the exact diagnosis and suspected anything from cold to cancer.
