Fear and Anxiety in Dogs: Drooling, Trembling, Assessment & Treatment [2025]
Fear and anxiety in dogs can lead to aggression, destructive behaviour, or separation anxiety. These issues are best improved through positive training, desensitisation, and environmental management. Severe cases may also need medication.

02How can you assess an abnormal change at home? Key observations and emergency warning signs
Systematic records at home help your vet assess severity, identify possible triggers, and decide whether referral to a behaviour specialist is needed.
- Record when the signs first appeared and how long they last
- Use your phone to record video and sound from triggering situations
- Track daily changes in appetite and water intake
- Note toileting frequency and whether accidents occur
- Mark the possible triggers and timing of each episode
- Arrange a veterinary appointment early to assess both behaviour and physical health
03How will a vet make the diagnosis? Common tests and assessments
Your vet will first rule out physical disease, then perform a behaviour assessment or arrange further tests and specialist referral if needed.
A full physical examination and observation of behavioural responses to stimuli
Blood tests and biochemistry to rule out metabolic or organ disease
Urinalysis to help check for infection or metabolic abnormalities
Advanced imaging, such as CT or MRI, if needed to assess the brain or other organs
Referral to a veterinary behaviour specialist or mental health care team if there are concerns
04What treatment and care are needed after diagnosis? Medication, diet changes, and home care
Treatment mainly focuses on behaviour modification and environmental changes, with medication when needed and regular rechecks to monitor response and side effects.
- Home environment changes plus desensitisation and counterconditioning training
- Medication or supportive therapy as recommended by your vet, with follow-up monitoring
- Diet and feeding schedule adjustments to support emotional and physical stability
- A small number of cases may need short-term hospital observation or close monitoring
- Regular rechecks to assess response and adjust the treatment plan as needed
- Referral to a behaviour specialist hospital or behaviourist for a second assessment if necessary
