Training
Giant Schnauzer
- They need 'No' to mean 'No' - not permissive training
- Be a confident leader - if you are passive, they will assume leadership
- They are intelligent problem solvers who will exploit inconsistency
- Socialization is a race against the clock before suspicion sets in
Great Pyrenees
- Must convince them your request is worth their effort
- Harsh corrections cause shutdown or defensive behavior
- Focus on management over strict obedience
- Accept that recall will never be 100% reliable
Giant Schnauzer Considerations
Male Giant Schnauzers are notoriously intolerant of other males, and females can be equally combative. This often emerges at sexual maturity (18-24 months), turning a peaceful puppy household into a war zone. Many owners end up 'crate and rotate' (permanent separation).
Unlike eager-to-please breeds, Giant Schnauzers constantly ask 'Why should I?' They test boundaries relentlessly. Passive or inconsistent owners will find themselves with a dog that assumes leadership, leading to resource guarding and territorial aggression.
Their heritage involves vermin control and cattle driving. The 'kill bite' part of the predatory sequence is often intact. Cats, rabbits, and small dogs are at significant risk.
Giant Schnauzers appear on many insurance 'dangerous dog' lists. Premiums may be 2-3x higher than average, or coverage denied entirely. Check insurance BEFORE getting this dog.
Great Pyrenees Considerations
The #1 complaint from suburban owners. Pyrs are genetically hardwired to patrol and bark at night - they were bred to ward off wolves and bears. This instinct cannot be trained out, only managed. Expect deep, booming barks at 2 AM when a leaf blows across the driveway.
Great Pyrenees do not believe in property lines. Without a secure 5-6 foot physical fence, they will expand their territory to include the entire neighborhood. They are notorious escape artists and will take the shock from invisible fences to pursue threats.
Adult Pyrs often exhibit severe aggression toward dogs of the same sex, particularly females. This usually manifests around social maturity (18-24 months). Opposite-sex pairs are generally recommended.
Pyrs are not dumb - they are independent. When called, they evaluate whether coming is more important than what they are currently doing (usually guarding). If they decide it isn't, they will ignore you completely.
Multi-Species Compatibility
| Species | Giant Schnauzer | Great Pyrenees |
|---|---|---|
| With Cats | High risk - only possible with strict supervision and early socialization, never guaranteed | Excellent - bred to protect vulnerable animals, views cats as part of the flock to guard |
| Small Mammals | Dangerous - strong prey drive | Good - low prey drive, protective instinct toward smaller animals in their family |
| Birds / Reptiles | Unsafe - predatory drive intact | Good with supervision - generally safe due to arrested predatory sequence |
Advanced Behavior
| Trait | Giant Schnauzer | Great Pyrenees |
|---|---|---|
| Predatory Sequence Risk | Full | Arrested |
| Biddability | Medium | Low |
| Noise Sensitivity | Low | Low |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | 18 months |
Giant Schnauzer: The predatory sequence (Eye->Stalk->Chase->Grab->Kill) is often intact from their vermin control heritage. They are true guard dogs who will physically confront threats - not just alert bark. They require an owner who can call them off immediately. Independent worker but cooperative with established handler.
Great Pyrenees: Predatory sequence arrested early - may chase predators to drive away but lack dissect/consume drive. Brilliant problem solvers but low 'working intelligence' (willingness to follow commands). Bred to work without humans so don't look to humans for answers.
First Year & Life Stages

| Adolescent Regression |
Giant Schnauzer: Unlike friendly Labs, Giant Schnauzer puppies combine sharp puppy teeth with a desire to dominate. They challenge handling early. Socialization is a race against the clock before their suspicion of strangers sets in. They are 'beavers' that will dismantle furniture if bored.
Great Pyrenees: Pyr puppies are large, stubborn land sharks. A 6-month-old is the size of a German Shepherd but has the brain of a toddler. Critical socialization window 8-16 weeks - must expose to strangers, other dogs, and strange noises or natural guarding instinct can turn into fear-aggression.
