Many dogs have a phobia of thunderstorms. Dogs are very sensitive and they can often know beforehand if bad weather is coming. Your dog can become anxious, hide or even start biting objects (hopefully not you!).
If you think your dog suffers from this phobia, don’t try to force them to go outside in attempt to get them to ‘face their fear’. And punishment is never a good idea either. If it gets very bad, the best option is to always contact your veterinarian. They can recommend great techniques to improve the behaviour of your dog so it can feel more relaxed when a storm is approaching.
Another reason that dogs can dislike bad weather is because the sound of rain can become amplified. It’s a common fact that dogs have very sensitive hearing. Instead of enjoying the rain as we do, they can find the noise very uncomfortable. In this case, try to keep your dog entertained, practice some tricks or just give him a warm cuddle to make them feel safe and relaxed.
