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
Scottish Sheepdog Longhair
- Keep sessions short (5-10 mins) and fun
- Harsh corrections will cause them to shut down or become fearful
- They are intelligent but not 'neurotic' about problem-solving like Border Collies
- Train 'quiet' command early to manage barking
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.
Scottish Sheepdog Longhair Considerations
Bred to communicate with shepherds over long distances, Collies alert to everything: delivery trucks, neighbors, squirrels, and wind. Unlike a guard dog's warning bark, a Collie often barks to chat or express boredom. The bark is sharp and piercing.
Exceptionally sensitive to their environment. Thunderstorms, fireworks, and even loud arguments can cause significant distress. Poor candidates for chaotic households with constant screaming or slamming doors.
The spectacular coat requires weekly 45-60 minute line-brushing sessions. Surface brushing leaves the undercoat to mat, leading to 'felted' dogs that must be shaved - a disaster for double coats. This is a hobby, not a chore.
Young Collies may attempt to herd running children by nipping at heels. This is an arrested predatory sequence behavior, not aggression, but it can be frightening for small children and requires management.
Multi-Species Compatibility
| Species | Giant Schnauzer | Scottish Sheepdog Longhair |
|---|---|---|
| With Cats | High risk - only possible with strict supervision and early socialization, never guaranteed | High safety - one of the best large breeds for multi-species homes. Low prey drive. |
| Small Mammals | Dangerous - strong prey drive | Generally safe - may try to herd but rarely has grab-bite instinct |
| Birds / Reptiles | Unsafe - predatory drive intact | Good with poultry if trained, though may harass if untrained |
Advanced Behavior
| Trait | Giant Schnauzer | Scottish Sheepdog Longhair |
|---|---|---|
| Predatory Sequence Risk | Full | Arrested |
| Biddability | Medium | High |
| Noise Sensitivity | Low | High |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | N/A |
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.
Scottish Sheepdog Longhair: Predatory sequence is Orient → Eye → Stalk → (Stop). They may stare at and follow cats but grab-bite is largely inhibited. They WANT to work with you - unlike Huskies who ask 'what's in it for me?' a Collie asks 'what do you want me to do?'
First Year & Life Stages

|---|---|---|
| Puppy Difficulty | ||
| Destructive Phase | 6-24 | 6-14 |
| House Training | Moderate | Easy |
| Crate Training | Medium | High |
| 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.
Scottish Sheepdog Longhair: Collie puppies are generally polite and observant, easier than Labradors or high-drive breeds. Main challenges are noise sensitivity and socialization to prevent shyness. May need ear taping for classic semi-prick look (cosmetic only).

Schnauzer Talk

Scottish Sheepdog Longhair Quirks
The Collie Nose
They use their long nose to poke, prod, and nudge you - their way of holding hands
The Greeter's Grin
