How to Evaluate a Shelter Dog's Temperament
Every weekend, thousands of owner-trainers walk into shelters with a mission: find a dog with the right stuff to become a legitimate service animal. Most leave with a dog they fell in love with. Far fewer leave with a dog that was actually suited for the job.
The gap between those two outcomes isn't about heart. It's about having a structured way to evaluate what you're looking at.
That's exactly what the Volhard Puppy Aptitude Test (PAT) was built for — and why PawForward uses it as the foundation of every canine evaluation. It's not a guarantee, but it's the closest thing to a reliable filter the dog training world has.
Why Temperament Matters More Than Breed
The instinct is to reach for breed as a shortcut. Golden Retrievers. Labrador Retrievers. German Shepherds. And yes, statistically these breeds do well in service work. But breed is a probability, not a promise.
A high-strung Golden from a neglectful background can wash out of service training faster than a calm, resilient mixed breed that nobody glanced at twice. Temperament is the actual predictor. Breed is just one of many factors that shapes it.
The AKC defines temperament as a dog's mental and emotional makeup — their natural disposition toward the world. For service work, you need specific qualities: biddability, low reactivity, bounce-back after stress, desire to engage with people. Breed can predict the likelihood of those traits. Temperament testing measures whether this dog actually has them.
That distinction matters a lot when you're evaluating a three-year-old shelter dog with an unknown history.
The Volhard Puppy Aptitude Test (PAT) — What It Measures
Wendy and Jack Volhard developed the PAT in the 1970s to help guide guide dog selection programs. Decades later, it remains one of the most widely used behavioral assessment tools in professional dog training. The Volhard training system has placed it at the center of structured dog evaluation worldwide.
The test is built around ten subtests, each scored on a 1–6 scale. The numbers represent a spectrum from highly dominant (1) to very submissive or independent (6). Neither extreme is ideal for service work — you're looking for scores in the 3–4 range across most tests, with occasional 2s or 5s.
Important: The PAT was designed for puppies aged 6–8 weeks. Adapting it to adult shelter dogs requires experience and judgment. The core principles hold, but your interpreter matters as much as the test itself.
What the PAT measures across its ten subtests falls into three categories:
- Social drives — How much does the dog want to engage with humans?
- Pack drive — How does the dog respond to authority, pressure, and correction?
- Prey/chase drive — How reactive is the dog to movement and stimulation?
For service dog work, you want strong social drive, moderate-to-low pack drive, and low-to-moderate prey drive.
The 10 Subtests Explained
Each subtest is conducted by a stranger to the dog — someone the dog has never met. This is critical. You're not measuring how the dog relates to you. You're measuring how it relates to people in general.
| # | Subtest | What It Measures | Ideal Score (Service) |
|---|---|---|---|
| 1 | Social Attraction | Willingness to approach an unfamiliar person | 3–4 |
| 2 | Following | Willingness to follow a moving person without being called | 3–4 |
| 3 | Restraint | Response to being held on their back (dominant or submissive?) | 3–4 |
| 4 | Social Dominance | Response to social pressure from a person leaning over them | 3–4 |
| 5 | Elevation Dominance | Response to being lifted off the ground by a stranger | 3–4 |
| 6 | Retrieving | Prey and chase drive; desire to fetch and return | 3–5 |
| 7 | Touch Sensitivity | Tolerance for physical discomfort (web between toes) | 3–5 |
| 8 | Sound Sensitivity | Response to a sudden loud noise | 3–4 |
| 9 | Sight Sensitivity | Response to a strange moving object | 3–4 |
| 10 | Stability | Overall stress response to an umbrella suddenly opening | 3–4 |
The scoring isn't just about the number — it's about consistency across subtests. A dog that scores 3 on eight subtests and 1 on two (extremely dominant in specific contexts) tells you something different than a dog with a clean 3–4 across the board.
Interpreting Your Results — Service Dog Potential
Once you have ten scores, add them up and look at the pattern. Here's what the ranges mean for service dog candidacy:
For most service dog tasks — mobility assistance, psychiatric support, medical alert — you want a dog in the 19–36 range with no scores of 1 (extreme dominance) and no scores of 6 (extreme submission or fear) on the high-stress subtests (Restraint, Elevation, Stability).
What a 28–36 looks like in practice: The dog approaches a stranger willingly but doesn't jump all over them. Follows a moving person with mild curiosity. Tolerates being lifted with a brief wiggle and then settles. Recovers from a loud noise within seconds. Returns to baseline after the umbrella pops open. Consistent, grounded, curious — not fearful, not pushy.
Red flags to walk away from: Any dog that growls, snaps, or freezes during restraint or elevation subtests. Dogs with extreme prey drive (score of 1 on Sight/Sound Sensitivity). Dogs that shut completely down under mild social pressure — they may seem "calm" but are actually dissociating from stress, which typically gets worse in public access environments.

Knowing a dog has the right temperament is step one. Building a legitimate, legally defensible service dog is the next 12–18 months of consistent, documented work.
PawForward's Masterclass ($299) walks owner-trainers through the full process — task training, public access, documentation, and the credentialing that separates a trained service dog from a dog in a vest. It's built specifically for veterans and owner-trainers who are serious about doing this right.
You've already done the hardest part by choosing to evaluate properly before getting attached. The Masterclass handles everything else.
