Common sources of pet stress
Providing essential key nutrients in the diet can help in dogs. Look for B Group vitamins that help maintain a healthy nervous system and tryptophan that helps to promote serotonin production (serotonin being well known to contribute to feelings of wellbeing).

If your pet already has anxieties or phobias, these are likely to escalate unless your pet is retrained. The way you act towards your pet at this time is critical. Be careful not to reward your pet by giving attention to stress behaviour, as this reinforces the ‘panic behaviour’ which can make their problem worse.
Instead, you will need to find a way to control, relax, calm or distract your pet in the presence of the stressful stimulus. This teaches them that there is nothing to be afraid of. Rewarding appropriate behaviour at times of stress by plenty of pats, toys and treats works well, reinforcing their response to stress. Alternatively, music, TV or radio background sounds can help camouflage noise anxieties (eg thunderstorms) and also help modify their moods.
If you think your pet is showing signs of stress you should consult with your veterinarian.
