Trazodone Dosage for a 100 lb Dog

Trazodone in dogs is typically dosed at approximately 2-10 mg/kg per dose, given 1-3 times daily as needed for situational anxiety, or daily for chronic anxiety. The wide range exists because individual dog response varies significantly — vets often start low and titrate up. For a 100 lb (45 kg) dog, this gives a range that a licensed vet will narrow down based on the indication, your dog's age, kidney/liver function, and any other medications.

Trazodone (trazodone) is widely used in dogs in the 100 lb range, but "safe" depends on the specific dog, not just the weight. Giant breeds have unique drug-metabolism considerations — they're not simply 'big small dogs.' They often need proportionally lower doses per kg than smaller dogs. Anesthesia, NSAIDs, and sedatives all need experienced veterinary calibration. Bloat (GDV) risk also affects which oral medications can be used safely. A licensed vet will check your dog's history, current medications, and any underlying conditions before prescribing.

The most common things to watch for are: Excessive sedation — the goal is calm, not unconscious; Wobbliness, especially first dose; Paradoxical agitation (rare but report immediately). If you see anything concerning, contact a vet. For giant dogs specifically: Giant breeds have unique drug-metabolism considerations — they're not simply 'big small dogs.' They often need proportionally lower doses per kg than smaller dogs.

Not after a video visit alone. Trazodone is a human-labeled drug, so a veterinarian needs to examine your pet in person before prescribing it.
