These symptoms could be indicative of several things:
* Allergies: Excessive licking and chomping at air are common signs of allergies, which can also cause weight loss.
* Parasites: Internal parasites can cause weight loss, while external parasites like fleas can cause intense itching and paw licking.
* Dental issues: Painful teeth or gum problems can make a dog lick their paws and chew at the air.
* Gastrointestinal problems: Conditions like inflammatory bowel disease (IBD) or pancreatitis can lead to weight loss, vomiting, and changes in appetite.
* Behavioral issues: Excessive licking can sometimes be a sign of anxiety or boredom.
What to do:
1. Schedule an appointment with your veterinarian immediately. They can diagnose the underlying cause and recommend appropriate treatment.
2. Keep a detailed record of your dog's symptoms. This will be helpful for your vet. Note:
* When did the symptoms start?
* How severe are they?
* Are there any other symptoms? (e.g., vomiting, diarrhea, lethargy)
3. Be prepared to answer questions about your dog's diet, exercise routine, and any recent changes in their environment.
Remember: Don't try to self-diagnose or treat your dog. Only a veterinarian can provide the best course of action for your furry friend's health.
