Viral Infections

Viral infections like canine influenza, respiratory coronavirus, adenovirus type 2, parainfluenza virus, and distemper can trigger dog congestion during sleep.

When viruses attack your dog’s airways, nighttime breathing becomes a battle against inflammation and swelling.

These dog respiratory infections cause swelling and inflammation in your pup’s airways, leading to dog cold symptoms including runny nose, coughing, and sneezing.

Dog upper respiratory issues from viral infections often worsen at night when lying down, which can be attributed to viral infections and lead to dog congestion.

Bacterial Infections

When viruses weaken your dog’s immune system, bacterial infections often follow.

Bordetella bronchiseptica causes kennel cough, while other bacteria can lead to bacterial pneumonia.

These secondary infections create thick, colored discharge and persistent symptoms that worry every pet parent:

1. Fever that makes your pup feel miserable
2. Loss of appetite leaving food bowls untouched
3. Lethargy replacing playful energy
4. Thick nasal discharge instead of clear
5. Persistent coughing that disrupts sleep

Antibiotic resistance makes infection prevention essential for your dog’s respiratory health. The presence of bacterial infections and persistent symptoms are key concerns for pet owners, and addressing these issues is crucial for maintaining your dog’s overall well-being.

Fungal Infections

Unlike bacterial culprits, fungal infections like Aspergillus create persistent respiratory troubles in your dog.
