What is the life span of a Newfoundland dog?
The usual lifespan of a Newfoundland dog is 8-10 years. Mainly because they are large dogs and end up hve heart or joint problems.
Larger breeds also have higher rates of osteosarcoma, an aggressive bone cancer that metastasizes rapidly. Newfies can be screened for sub-aorta problems, joint problems can be reduced if they are kept trim. Do NOT overfeed your Newfies, no matter how much they give you that look.
Is the life span of a dog 15-17 in human years?
A dog's life span depends on the breed. A feature that factors prominently into this is the size of the dog. Generally the larger the dog, the shorter the life span. Some small dogs can live to be twenty years or older but larger dogs can have a life span of only three to four years. I would say the average is around ten years.
The difference between a life cycle and a life span?
There are many types of cycles but I'm going to assume you're talking about the life cycle, life cycle is continued and never stopped until the creatures all have pass away. The life span is an average life time usually in years, like the hamster/gerbil life span is 3-4 years a dog life span is 12-14 years. The life cycle would just be, well life.
