Hmm... may I ask what is the breed type?I put some music through the speakers and he started circle pacing again and trembling
I was just reading this;
Certain breeds of dogs are overrepresented when it comes to noise phobias, strongly suggesting that there is an inherited component to this condition. It is thought that German Shepherds, Australian Shepherds, and Border Collies are genetically prone to these phobias.
There are various products, such as noise cancelling headphones for dogs, compression garments, and calming pheromones that may be helpful in calming some dogs.
As always, it is best to have your dog examined by your veterinarian when any fearful behaviour develops. Your vet will want to run lab work to make sure there isn’t an underlying health condition, such as hypothyroidism or Cushing’s disease that may be contributing to the abnormal behaviour. Your veterinarian can also consult you on supplements or medications that may be useful in managing noise phobias.
