my rottweiler x mastiff is now 16 months old but still behaves like a puppy!
he demands attention all the time and still cries when i leave the room.
we also have a 2 year old rottweiler who behaves really well.
they have both been brought up the same way but the younger one is still hard work.
Big dogs like Rottweilers and Mastiffs are slow to mature, and at 16 months old your younger dog is still very much a puppy.
Also, dogs are just like people – they’re all different and unique, with their own personality traits. Your Rottie mix is obviously just a little more needy than your Rottweiler boy, plus he’s still an adolescent, whereas your older boy is almost adult.
Neither personality is ‘better’, they’re just different and probably always will be. Rottweilers may be big dogs, but they’re very loving, loyal and affectionate and tend to think that they’re lap dogs! I honestly think they have no idea of their size, and obviously don’t believe all the nonsense and ‘hype’ out there that says they’re these vicious, aggressive ‘bad boys’ 🙂
Some big males are not fully mature until around 2 1/2 to 3 years old, and the bigger the dog breed the longer it takes them to mature. Your Rottie mix is half Mastiff so may be slower to reach adulthood than your purebred Rottweiler.
Just continue to socialize and train them and raise them both with lots of love and loving discipline and they’ll each reach their own individual potential given time. They look like an adorable pair and I wish you the very best of luck with your dogs.
