The best rule of thumb is you will know when they want to go for a walk as they may become destructive.

These dogs will need around one hour of exercise each day to keep them healthy and mentally stimulated.

Most Mastiffs are well-known for letting their owners know when they are tired on walks by plonking themselves down and not getting back up.

  • Proteins are essential to a dogs’ diet, this provides them with amino acids they cannot produce themselves
  • Dogs also need dietary fats to give them energy
  • They also need a variety of minerals and vitamins to stay healthy

How much you feed your dog is dependent on their forecasted adult weight. A Pitbull Mastiff Mix is a big dog, so they will need more food than the average dog; around 4.5 cups of kibble for 100lb.

You can spread this over 2-3 meals a day for a mature dog and always ask your vet if you have any doubts.

When you see a puppy you like, contact the breeder to ask to see them with mom and the litter. If they don’t let you see her, chances are they are not trustworthy.

Seeing mom is important because mom’s maternal care towards the puppy can affect a puppy’s behavior. Low levels of maternal care can cause the puppy to develop unwanted behaviors – you want to make sure this puppy was cared for by mom!

When you meet with the breeder, ask them questions like: what are you feeding the puppies, what kind of socialization have they been exposed to, how many litters has mom had?

They will also provide health certificates for mom (specifically hip and elbow scores) and will let you know if the puppy’s vaccinations are up to date.

As this is such a large dog, the breeder should take part in genetic screening to prevent hip dysplasia genes being passed on from parents to puppy.

Puppies should be at least 8 weeks old to leave mom and come home with you.
