- Live in an apartment or rental
- Have close neighbors sensitive to barking
- Want a dog that obeys commands instantly
- Don't have a secure physical fence
- Want a pristine, fur-free home
- Need a running or high-intensity exercise partner
Scottish Sheepdog Longhair Dealbreakers
- Cannot tolerate barking
- Want a 'wash and go' dog - grooming is a hobby here
- Want a dog to jog 10 miles with you in July
- Use harsh training methods - they are 'soft' dogs that shut down
Surrender Risk
| Factor | Great Pyrenees | Scottish Sheepdog Longhair |
|---|---|---|
| Risk Level | High | Low |
| Primary Reasons | Nocturnal barking - owners get a fluffy puppy that starts barking all night at 1 year old, Roaming/escape - jumping fences to expand territory, Resource guarding - growling over food scares families who expected Golden Retriever temperament, Size underestimated - 120lb dog that refuses to move and may growl when asked to get off couch | Barking - underestimated volume and frequency, Shedding/Grooming - extreme hair and time commitment, Lassie Effect - unrealistic expectations from TV show |

Training
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
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
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.
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 | Great Pyrenees | Scottish Sheepdog Longhair |
|---|---|---|
| With Cats | Excellent - bred to protect vulnerable animals, views cats as part of the flock to guard | High safety - one of the best large breeds for multi-species homes. Low prey drive. |
| Small Mammals | Good - low prey drive, protective instinct toward smaller animals in their family | Generally safe - may try to herd but rarely has grab-bite instinct |
| Birds / Reptiles | Good with supervision - generally safe due to arrested predatory sequence | Good with poultry if trained, though may harass if untrained |
Advanced Behavior
| Trait | Great Pyrenees | Scottish Sheepdog Longhair |
|---|---|---|
| Predatory Sequence Risk | Arrested | Arrested |
| Biddability | Low | High |
| Noise Sensitivity | Low | High |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | N/A |
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.
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
First Year Challenges
| Challenge | Great Pyrenees | Scottish Sheepdog Longhair |
|---|---|---|
| Puppy Difficulty | ||
| Destructive Phase | 6-18 | 6-14 |
| House Training | Medium | Easy |
| Crate Training | Medium | High |
| Adolescent Regression |
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.
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).

White coat is surprisingly self-cleaning (mud dries and falls off) - but the mud falls off onto your floor
Selective Deafness
Will evaluate your command, decide if it's worth their effort, and ignore you if it isn't
Snow Obsession
Will refuse to come inside during snowstorms - thrive in freezing temperatures
Scottish Sheepdog Longhair Quirks
