Due to its effectiveness against intracellular bacteria, and bacteria without cell walls, which of the following antibiotics is commonly used as a first-line treatment for bacterial upper respiratory tract infections?

What differentiates asthma from chronic bronchitis in cats?
- Whether the inflammation is neutrophilic or eosinophilic (asthma is eosinophilic)

An alveolar pattern in the gravity-dependent cranial and ventral lung lobes
common predisposing condition in adult dogs with aspiration pneumonia?
Megaesophagus
Which drugs are generally contraindicated in the treatment of bacterial pneumonia?
- Diuretics - can cause dehydration, hydration needed to optimized mucociliary clearance
- Cough suppressants - coughing helping clear debris

Ned is an 18-month-old male castrated Labrador whose owners recently returned from a skiing vacation in Aspen. While they were skiing, Ned was staying at PetsParadise4Dawgs boarding establishment. He is just overdue for his routine vaccinations. Upon returning, the owners noticed right away that he had a loud, dry-sounding cough and a runny nose. The clinical signs started 5 days ago. He is still his normal energetic self and has a normal appetite with no vomiting or diarrhea. Considering his signalment, history and clinical signs, which differential diagnosis do you think is MOST likely?
Canine infectious respiratory disease complex (kennel cough)
rule outs
- canine chronic bronchitis - duration
- aspiration pneumonia - systemic signs
- CHF - age and no heart murmur
How is Canine infectious disease complex diagnosed?
Clinical signs and history
