It is possible for canines to suffer panic or anxiety attacks, just like humans can. While this can be due to past abuse and other terribly negative experiences, this is not true in all cases.
A dog can be raised in a wonderfully loving home, but still have these sorts of issues. In some cases, this is due to a chemical imbalance in the brain.
So, if the above guidelines do not bring about improvement, or if you think that your Beagle's anxiety is at a severe level, it will be time to seek professional help from the veterinarian.
Some of the more commonly prescribed medications to help dogs with anxiety include alprazolam, amitriptyline, buspirone, clomicalm, dexmedetomidine (Sileo), diazepam, fluoxetine (Reconcile), lorazepam, paroxetine, and sertraline.
The veterinarian will assess which triggers are causing your dog distress and prescribe the most appropriate treatment.
These can have some side effects, so this is something that you will want to discuss with the vet.
In some cases, just a short duration of 4 to 6 weeks is all that is needed. Other times, a dog may need to stay on a low dose.
