A rapid heart rate means your dog's body is overheating. Check their pulse and if it seems like it is too fast or too heavy, then you should take them to the vet immediately without hesitating. Especially when coupled with any of these other symptoms, rapid heart rate can be very dangerous.
How can I calm my dogs heart rate?
Most of the time, dogs will require medication, such as lidocaine and sotalol. Another technique is the vagal maneuver, which involves ocular or carotid sinus pressure to stimulate the vagal nerve, which slows heart rate.
