In animals claustrophobia is not really found or mixed with neurosis or social influence, but there is a genetic basis and a lack of good early experience with closed spaces such as crates, cars and rooms.
The genetic basis is based on type and independence. Classified dog breeds such as working, guarding, sports and hunting areas will not be able to tolerate enclosed areas so training any puppy in these categories will have to start early; usually from six weeks of age onwards, which is the end of weaning.
Other possible claustrophobic species are Robermann Pinscher, Border Collie, Siberian Husky, Belgian Shepherd, German Shepherd, Jack Russell Terrier, Bernese Mountain Dog, Airedale Terrier, Basset Hound, Beagle, Dalmatian, Rhodesian Ridgeback, Wearara-ner, Irish Setter, I -English Springer Spaniel, Golden Retriever, Labrador and Boxer.
One of the reasons why veterinarians and veterinarians promote puppy contact and basic listening training is to teach young animals future co-operative skills in life. One of the coping skills that a child should be taught is to accept and tolerate confinement where they may be hospitalized, boarded or transported. One should only look at the dogs in these restricted facilities to judge which animal has a responsible owner.
