The Australian Shepherd needs slightly more exercise (5/5) than the Pembroke Welsh Corgi (4/5), but neither breed is at an extreme. Both have very high to high energy levels, so the difference in your daily routine will be modest — perhaps an extra 15-20 minutes of activity for the Australian Shepherd.

Lifespan is a near-tie: the Australian Shepherd lives roughly 13–15 years while the Pembroke Welsh Corgi averages 12–15 years. Neither breed has a clear longevity advantage, so other factors should drive your choice.

These two breeds look nothing alike. The Australian Shepherd is a medium breed at 18–29 kg (40–64 lbs) and 46–58 cm (18–23 in), while the Pembroke Welsh Corgi is a small breed at just 10–14 kg (22–31 lbs) and 25–30 cm (10–12 in).

Personality is where these two breeds diverge most visibly. The Australian Shepherd — an American breed — has a intelligent, energetic and loyal disposition.

Purchase prices are in the same ballpark: $800–$2,000 for a Australian Shepherd and $1,000–$2,500 for a Pembroke Welsh Corgi. The initial investment won't differ dramatically between these two breeds.

Both breeds shed at the same rate (4/5), so fur management will be identical for either choice. Budget for a good robot vacuum.

The Australian Shepherd has a slight training edge (5/5 vs 4/5). Both respond to positive reinforcement, but the Australian Shepherd tends to catch on a bit faster.

Both breeds score 4/5 with children, making them equally suitable for families. Either breed would make an excellent family dog.
