Ideally, you should have a fenced in garden that your dog can go in and out of at will, they tend to exercise in short bursts of running around followed by hours of sleeping.
When your Great Dane is young, it is best if they exercise in short bursts of energy, playing with you in the garden. You do not want them to go for walks of more than a mile or two during the first 12 months as they are growing so rapidly and you do not want to put unnecessary strain on the bones and joints. A Great Dane is not fully matured until two years of age.
In an ideal world, the Great Dane should be walked on a leash twice a day; this doesn’t need to be too long, especially in warm weather as it does not take much heat to get him panting heavily.
Suitability as a family pet:
Just like other breeds, this breed needs a proper diet to keep him nourished and proper care and grooming to maintain the health and appearance. It is also the owner’s responsibility to protect the pet from minor to life-threatening diseases by having them vaccinated and giving them safe and comfortable sleeping area. But protection for pets could extend beyond that. We all know that health problems may arise any time no matter how hard we try to protect our dear dogs. They may need to see and be treated by vets to nurse them back to good health and lengthen your happy years together. Vet bills may sometimes rise rapidly and soon you can no longer afford to pay those bills. Pity for those animals whose owners aren’t wise enough to get a pet insurance for them.
