Do Mastidoodles shed?

Low shedding

No — Mastidoodles shed very little. This is one of their most appealing traits for people who'd rather not hoover twice a day. They're also considered hypoallergenic, making them a good option for people with mild dog allergies. You'll still want to brush them regularly to keep their coat healthy, but you won't find hair on every surface you own.

Are Mastidoodles good with kids?

Good with kids

Yes — Mastidoodles are famously gentle with children. They tend to be loyal and calm, which makes them a natural fit for busy family life. Always supervise any dog around young children, regardless of breed. Their size means they can accidentally knock small children over, so supervision around toddlers is important.

Are Mastidoodles good with cats?

Strong prey drive

Mastidoodles have a strong prey drive and will often chase cats. Given their size, this can be dangerous for a cat. It\'s not impossible to have a Mastidoodle and a cat together, but it takes careful management — separate spaces, slow introductions over weeks, and never leaving them unsupervised until you're absolutely certain they're safe together. Some Mastidoodles raised with cats from puppyhood learn to coexist, but the prey drive is rarely fully extinguished.

Are Mastidoodles easy to train?

Moderate training

Mastidoodles are moderately trainable — capable dogs, but they have opinions and will test boundaries. Positive reinforcement works well. Avoid harsh corrections, which can make them shut down or become anxious. Consistency is the key word with this breed. Everyone in the household needs to use the same rules and commands, or they'll find the inconsistency and exploit it.

Do Mastidoodles bark a lot?

Quiet breed

Mastidoodles are a quiet breed — they rarely bark without a good reason. This makes them an excellent choice for flat or terraced-house living where noise is a concern. They might bark to alert you to someone at the door, but sustained, excessive barking is uncommon. Neighbours tend to be fans.

Are Mastidoodles hypoallergenic?

Hypoallergenic

Mastidoodles are considered hypoallergenic — they produce significantly less dander than most breeds. No dog is 100% allergen-free (the allergen is a protein in saliva and skin, not just hair), but Mastidoodles are much better tolerated by people with dog allergies. If allergies are a concern, spend time with a Mastidoodle before committing. Visit a breeder or a friend who owns one — if you're fine after an hour, you'll likely be fine long-term.

How much exercise does a Mastidoodle need?

Mastidoodles need 30–45 min/day of exercise daily. They're a relatively low-maintenance breed in this respect — shorter walks suit them fine, and they're perfectly happy with a relaxed routine. Good for owners who can't commit to marathon exercise sessions daily.

Mental exercise matters as much as physical. A Mastidoodle with a bored brain will find its own entertainment — usually involving your sofa or your shoes. Training sessions, puzzle feeders, and nose-work games all count.

Mastidoodle health problems

Like all breeds, Mastidoodles are prone to certain conditions. Knowing about them upfront means earlier detection, better outcomes, and fewer surprise vet bills.

As a giant breed, Mastidoodles are particularly susceptible to bloat (GDV) — a life-threatening condition where the stomach twists. Learn the signs: unproductive retching, distended abdomen, restlessness. It requires emergency surgery. Feeding two smaller meals rather than one large one helps reduce risk.

  • Hip dysplasia. Common in larger breeds, causes arthritis and mobility issues. Check parents have been hip-scored.
  • Elbow dysplasia. Similar to hip dysplasia, affects the front legs.
  • Obesity. The most preventable health problem across all dog breeds. Keep them at a healthy weight.
  • Annual vet checks. Catching problems early makes all the difference.

How long do Mastidoodles live?

Mastidoodles typically live 8–12 years. Unfortunately, giant breeds have significantly shorter lifespans than smaller dogs — the toll of maintaining such a large body accelerates ageing.

Lifespan is heavily influenced by weight management, exercise, genetics, and access to regular vet care. A Mastidoodle at a healthy weight, with good genetics and regular check-ups, will typically live toward the top of that range.

How much does a Mastidoodle cost in the UK?

A Mastidoodle puppy from a reputable KC-registered UK breeder typically costs £1 500–£4 000.

If you see a Mastidoodle puppy advertised for significantly less than £1 500, be very cautious. Low prices are the most common red flag for puppy farms.

The purchase price is just the start. First-year costs typically include:

  • Vaccinations: ~£80–120
  • Neutering/spaying: £200–400 depending on size and vet
  • Microchipping (mandatory in UK): ~£20–30
  • Bed, crate, leads, collar: £100–250
  • Food (per year): £400–£1,200+ depending on size and diet
  • Pet insurance: £70–£160/month (see below)
  • Routine vet visits: £50–200/year

Total first-year cost beyond the puppy price: typically £1,500–£3,000.

Mastidoodle pet insurance

Pet insurance for a Mastidoodle in the UK typically costs £70–£160/month for comprehensive lifetime cover.

Lifetime cover is strongly recommended over cheaper time-limited or maximum-benefit policies. Once a condition is diagnosed and treated, lifetime cover continues to pay for it every year. Time-limited policies exclude it after 12 months — exactly when chronic conditions become expensive.

Compare quotes from Petplan, ManyPets, Waggel, and Animal Friends — all have strong reputations for actually paying out claims. Always check the annual limit (aim for £7,000+ per condition) and whether hereditary conditions are covered.
