Frequently asked questions

How much does a Dogo Argentino cost?
Reputable US breeders typically charge $1,500-$4,000 for a pet-quality, BAER-tested puppy; proven hunting or show lines cost more. Over a 10-12 year life, food and routine care for a 40 kg dog commonly add $20,000-$30,000+, and note that liability insurance can be harder or pricier to get with this breed.
Is the Dogo Argentino banned anywhere?
Yes. The breed is banned or restricted in several countries (including the UK) and in various US cities, counties, and housing policies. Before buying, verify your local ordinances, your lease, and your homeowner's or renter's insurance - rehoming a banned breed later is painful for everyone, especially the dog.
Is a Dogo Argentino good with other dogs?
This is the breed's weakest point. Dogos were bred to hunt big game in packs but same-sex aggression is well documented, and many adults do not tolerate strange dogs. Early, ongoing socialization helps, yet dog parks remain a bad idea for most Dogos. Plan for a one-dog household or careful lifetime management.
Is a Dogo Argentino a good first dog?
No. It is not that the breed is unmanageable - it is loyal, trainable and stable in the right hands - but it combines serious strength, high prey drive and guarding instinct. Mistakes that a Labrador forgives become dangerous at this size and power. Get experience with a strong breed first, or work closely with a professional trainer from day one.
