The American Mastiff Panja, being a large dog, needs a lot of food to supply its daily calorie requirement of between 1500-2000 calories for optimal health. 

Full-grown American Mastiff Panjas need about 6-10 cups of dry food. However, the precise amount for your dog will depend on factors such as the sort of food it takes and other health conditions. Growing puppies and nursing mothers may require significantly more food, whilst senior mastiffs need much less. To avoid bloat, the food for a Panja should be divided into 2 or 3 meals per day.

The following classes of Mastiffs (Panjas) will need different amounts of food as follows:

  • Nursing Mastiffs Panja: An American Mastiff Panja who is nursing babies needs more food to enable optimal milk production for feeding its litters. As such, they should feed between 9-12 cups of high-quality kibble.
  • Unspayed/ unneutered Mastiffs (Panja): American Mastiffs Panja who are still intact have higher metabolisms than spayed or neutered ones. They, as such, require 8-10 cups for males and 7-9 cups of food for females.
  • Senior Mastiffs Panja: It’s crucial to make changes to an American Mastiff’ Panja’s nutrition as it advances in age. You’ll hence need to switch to an appropriate senior-specific diet. 5-7 cups of food are ideal for these dogs.

The following tests are necessary for an American Mastiff (Panja):

  • Bloat: Also referred to as gastric torsion, this is a potentially fatal condition that commonly occurs in huge, deep-chested dogs. This usually occurs if dogs are fed on a single meal all at once when dogs quickly gulp down their food without chewing properly, or they exercise too vigorously after eating. This causes the stomach to expand with gas or air. As a result, the dog’s blood pressure goes down causing shock. The symptoms of bloat include a distended stomach, lethargy, body weakness, and fast heart rate.
  • Hip dysplasia: This is a hereditary condition that occurs when the thigh bone doesn’t fit well in the hip socket causing pain and lameness to the dog. Although it’s a hereditary disease, certain environmental factors such as rapid growth resulting from feeding a calorie-dense diet or injuries from jumping on steep stairs. This condition highly limits the movement and mobility of dogs.
  • Cancer: The American Mastiffs are prone to bone cancer also referred to as osteosarcoma. This is initially marked by lameness. This condition needs aggressive treatment methods such as amputation

Additionally, American Mastiffs Panja is prone to obesity. Being large dogs, they have high-calorie needs and need a lot of food. However, it’s important to exercise caution as too many calories can cause unhealthy weight gain in Mastiffs Panja.

  • Dental health issues: An American Mastiff Panja can have bad breath if it suffers from dental problems such as gum and teeth infection or periodontal disease.

Panjas can whine and cry loudly if you left at home. To avoid this, they need proper training to cope with this. To do this, you can begin by going out, closing the door, and coming back after a few minutes. Then, lengthen the period so that the dog can learn that you will eventually come back. Without proper training, Mastiff Panja can develop separation anxiety. 

Can an American Mastiff (Panja) be left alone for 8 hours?

No, Mastiffs should not be left alone for 8 hours. Depending on their age, these dogs should not be left alone for more than 1 hour per their age. As such, a Mastiff puppy at the age of two months should be left alone for a maximum of two hours only.

It’s important to follow this rule until the puppy attains the age of eight months. At this point, they are fully potty trained and capable of surviving the day. Therefore, Panjas should not be left alone for more than 8 hours.

If you can’t avoid leaving your Mastiff for 8 hours or more, you should consider bringing in a family member, friend, or pet caregiver to look after the dog while you are away. Taking the dog for a walk is a great way of giving them the much-needed break from day-long loneliness which can enhance their wellbeing.

How to Train an American Mastiff (Panja)?

American Mastiffs (Panjas) are extremely intelligent and can quickly learn various commands. However, due to their dominating nature, training this dog can be quite challenging, most especially to inexperienced, or novice dog owners. It’s very difficult to get an American Mastiff to do something it doesn’t want to. As such, it requires an assertive owner who is capable of displaying his authority over this dog. Treats will come in handy when training an American Mastiff.

The training of an American Mastiff ( Panja) should begin immediately after the puppy is brought home. This is because as puppies, Mastiffs can quickly pick up commands.  Waiting until they are adults will make training incredibly difficult.  At two months of age, Mastiff puppies can begin their training.

While training an American Mastiff, the owner must be firm and establish himself as the pack leader over these dogs from the start. Otherwise, unassured or weak leaders may find it very difficult to get these dogs to accept their directions. The training must also be consistent to prevent the Mastiff from establishing itself as the leader.

The Mastiff owner should begin by teaching his puppy that he’s the leader, then introduce between 2-4  new orders. It should begin with simple gesture-activated clues before gradually advancing to more complex word-driven directives.

It will take a Mastiff puppy up to seven months of training to fully learn basic commands. Learning and responding to advanced commands, will, on the other hand, take an extra three to six months. These dogs should have mastered a suitable level of training at this point.
