Loud noises, unfamiliar persons or animals, visual stimuli like hats or umbrellas, new or strange locations, specific scenarios — like the vet's office or car rides — or surfaces like metal plates, gates or wood floors can all trigger fear-related anxiety. Although some dogs may simply have brief reactions to these stimuli, they may have a greater impact on dogs more prone to being anxious, insecure or timid.
Around 14% of dogs are thought to suffer from separation anxiety. When dogs with separation anxiety are left alone or separated from their family, they are unable to find solace. Unwanted behaviours such as urinating and defecating in the house, destroying furniture and furnishings, and barking are common manifestations of anxiety.
