The following homeopathic remedies can be used to treat anxiety in dogs:
- Aconitum: Fear and restlessness following a frightening event. This remedy may help gun-shy dogs that were not properly habituated to gunfire, or dogs that had a frightening experience at the kennel or the vet’s office.
- Argentum nitricum: Anticipatory anxiety, often with trembling and loose bowels. This is useful for show nerves in horses and dogs (and people).
- Belladonna: Extreme fear with dilated pupils and aggressive behavior. This is the classic picture of a feral cat caught in a trap, or an agitated animal crouched in the corner of a room or an animal carrier.
- Ignatia: Hypersensitivity, muscle twitches and moodiness. The animal may have a history of recent grief, loss or rehoming (changing families). These animals may sigh or whine a lot, and they can be irritable.

- Lachesis: Restless, sensitive to all stimuli, talkative and jealous. Some animals, especially dominant ones, behave like this with a new addition (animal or human) to the household.
- Natrum muriaticum: Moody outbursts, depressed and withdrawn. The animals don’t play well and often have a history of rehoming or loss.
- Nux vomica: Impatient, fearful and sensitive to stimuli. These animals may be the boss of the house in many situations, bullying the other animals and being demanding of people; yet a thunderstorm or a strange package in the house can cause them to tremble.
- Staphysagria: Gentle animals with angry or fearful outbursts. They are typically the low animal on the totem pole that wouldn’t hurt a fly, so their outburst is all the more surprising
