For toy size dogs, 15 is equivalent to 70 human years.
For small size dogs, 15 is equivalent to 76 human years.
For medium size dogs, 15 is equivalent to 83 human years.
For large size dogs, 15 is equivalent to 70 human years.
For giant size dogs, the information is not available for a dog that is 15 years old.
Experts agree, however, that the level of maturity a dog reaches in the first two years is similar to that of a 14-year-old human, but that is where the similarity ends.
Converting dog years to human years depends on various factors as toy, small, medium, large and giant dogs mature differently.
The age of a pup in dog years to human years depends on the following: Breed Size Weight Activity level Diet Lifestyle Health Lifespan.

Some changes in your pet's behaviour, such as slowing down, sleeping more and being a bit less mobile are often considered to be normal due to age but often indicate underlying pain or discomfort such as arthritis.
If your dog is older, why not book a senior health check to discuss their changing needs with your veterinary team?
Changes in appetite, excessive drinking and eye or teeth problems also need to be dealt with by your vet.
