How to help a weather sensitive dog?He used to start shaking & panting when it thundered,but gradually shook with the onset of rain.He starts to shake & pant well before the rain starts.Seems to be affected by geometrical forces.Have tried medication.Want to try de-sensitising cd,but can't find one.Hope someone can help.If it is geometrical,how can I combat this?He is a 5 year old maltese x poodle.Has been like this for about 3years.Don't know what triggered it off.
