Most pitbulls have atopic dermatitis (environmental allergies). One of the main symptoms of allergies in dogs is licking/chewing at the paws and scratching everywhere. Often allergic dogs also have chronic allergies and recurring anal gland issues too. I recommend making an appointment with your vet about possible allergies. There is an allergy medication called Apoquel that doesn’t have the same effects as steroids on increasing thirst and peeing, but usually works on significantly alleviating the itch within a few hours. There is also an injectable allergy medication called Cytopoint that is given every 4 weeks and can be given in conjunction with Apoquel that has had amazing results in most atopic dermatitis dogs. While on these allergy meds, Vega should be on an oral flea and tick medication such as Bravecto, Simparica or NexGard as even a single flea bite can cause a similar allergic reaction. The trembling and vomiting may be due to a food allergy, acid reflux or possibly a liver/kidney issues. Yearly screening bloodwork is recommended to rule out more serious internal organ causes of the vomiting. A trial switch to a prescription diet such as Royal Canin GI may be recommended by your vet as well. Good luck!
