Here's what you should do:
1. Assess the situation:
- Is the swelling localized (just the face) or more widespread?
- Does your dog seem to be in pain?
- Has your dog been exposed to anything unusual (new food, insect sting, etc.)?
2. Contact your veterinarian:
- Call your vet's emergency line or the emergency animal hospital in your area. They can advise you on the best course of action.
- Even if the vet is closed, they might be able to direct you to an emergency clinic or provide basic advice over the phone.
3. If your dog is showing signs of distress or difficulty breathing, seek immediate veterinary care.
Don't wait to see if it gets better! Acting quickly could be vital to your dog's health.
