Deep dive
Size and build
These two are closer cousins than most pairings on this site, but the Collie is the bigger dog: 50-75 lbs and 22-26 inches, a full size class up from the Aussie's medium 40-65 lbs and 18-23 inches. Both carry the classic herding-dog build; the Collie is simply a larger-framed version of it.
Energy and exercise
Despite sharing a herding background, the two don't need equal exercise. The Aussie rates a very high 5/5, the Collie a more moderate 3/5 -- closer to a family dog's needs than a working dog's. Energy level shows the same gap (5 versus 3) even though the table lists it as a tie, so don't assume related breed means same activity level.
Grooming and shedding
The Collie's long double coat pushes its grooming rating to a high 4/5, above the Aussie's moderate 3/5, though both shed heavily at 4/5. If coat care is your deciding factor, the Aussie's medium-length coat is the lighter lift of the two, despite what the similar shedding scores might suggest.
Apartment living, noise and time alone
Neither breed is a strong apartment candidate, but the Collie edges out the Aussie -- 2/5 for apartment suitability against a very low 1/5. Barking ties at a moderate 3/5. This is one of the few categories on this page where the difference reads more as both are tough than one is clearly better.
Training and owner experience
Both breeds train exceptionally well, tying at a very high 5/5 for trainability -- no surprise, given how closely related they are. Where they split is owner-friendliness: the Collie rates a high 4/5 for first-time owners against the Aussie's low 2/5, and tolerates being alone better too (3/5 versus 2/5). The Collie is the gentler on-ramp into this general breed type.
Kids, other dogs and visitors
The Collie pulls ahead across the board here: very high with kids (5/5 versus 4/5) and high with strangers (4/5 versus the Aussie's low 2/5), with both tying on compatibility with other dogs (4/5). Its intelligent, gentle, sensitive temperament reads as the more social of the two, matching a busier household better than the Aussie's more reserved nature.
Health and lifespan
Lifespan slightly favors the Aussie, 12-15 years against 11-14 for the Collie. Health overlap is heavy for this pair -- six conditions appear on both lists, including hip dysplasia, progressive retinal atrophy, epilepsy, collie eye anomaly, hypothyroidism, and cancer, which tracks with how closely the two breeds are related. The Collie's list adds bloat and gastric torsion, conditions not flagged for the Aussie.
Cost to keep
Cost is essentially a wash: both land at a moderate 3/5, both run $100-$200 monthly, and both fall in the same $1,500-$2,800 first-year range. If cost were your only deciding factor between these two, the data offers no tiebreaker -- the choice comes down to temperament and exercise tolerance instead.
