How to Prepare for Your Dog’s Blood Test
To help your pet’s appointment go as smoothly and safely as possible, please follow the guidance below.
Pre-Visit Anti-Anxiety Medication
To make the visit as calm and stress-free as possible, we may recommend giving anti-anxiety medication at home before the appointment.
If we have examined your pet within the last six months, we may be able to prescribe pre-visit medication to help reduce stress, fear, and reactivity during veterinary visits — making handling, examinations, and treatments much more comfortable for them.
Unfortunately, we are unable to prescribe these medications for pets we have not seen recently.
For dogs, we may recommend:
-
Trazodone
-
Trazodone & Gabapentin
-
Medetomidine Gel
This depends on your dog’s individual needs, size, and temperament.
Timing
Medication is typically given 2 hours before the estimated time of the appointment, when its calming effects are most beneficial. Effects usually last 6–12 hours, although this can vary between pets.
Because response and metabolism differ — depending on weight, temperament, and medical history — some pets may require an adjusted dose. In some cases, if the initial dose has begun to wear off, we may advise a small “top-up” (microdose) to maintain the calming effect.
We will always guide you clearly on dosing and timing beforehand. You are very welcome to contact us if you are unsure at any stage.
Fasting Before the Appointment
-
Please ensure your pet has no food for a minimum of 8 hours before their appointment. This is important in case a mild sedative is required or if certain blood tests are being run.
-
Water should be taken up 2 hours pre appointment however if your pet has any health conditions or the weather is hot please seek guidance from the vet on this.
Holding Dogs for a Blood Test
Dogs are usually more comfortable being positioned in specific ways for stability and reassurance.
-
Most dogs are gently straddled into the corner of a room or table for support.
-
They may need to wear a muzzle for safety.
Blood is commonly taken from:
-
The neck (jugular vein), or
-
The front leg (cephalic vein)
A handler will:
-
Stand over or beside the dog
-
Keep them close to their body
-
Hold the head or leg steady
-
Position them into the corner of a room or table
For more nervous dogs we recommend having two confident handlers. One handler to gently straddle the patient and the other to assist with distraction and calming. Sometimes gently holding a light towel over the eyes can help reduce fear as well as gentle soothing voice reassurance. Treats can also be used as a distraction method.
This positioning helps dogs feel supported and prevents backing away.

During the Visit
Small changes can make a big difference in reducing stress:
-
Have high-value treats ready and easily accessible
-
Ensure no children or other animals are in the room during the consultation
-
Consider playing calm, classical music to create a relaxed atmosphere
Non-slip mats or towels are helpful for nervous pets.
If you have any questions or concerns before your appointment, please don’t hesitate to contact us — we’re happy to help make the visit as stress-free as possible for both you and your pet.
