What's the life expectancy for a 7-year-old medium mixed-breed dog?

Large-giant breed types age faster and have a lower life expectancy of 8-10 but cross breeds can be much hardier than true st bernards. Again maintaining a healthy lifestyle and regular checks ups are important to highlight any changes as they age http://www.akc.org/content/entertainment/articles/how-to-calculate-dog-years-to-human-years/

Larger dogs do age more quickly than smaller dogs. In the case if your dogs I would say your seven-year-old is ‘middle-aged’ and would consider him a senior dog at about 9 or 10 years of age. The larger dog, Tasha I would say would be middle-aged at about 6 years old. And would consider her a senior dog at age 7 or 8. However, keep in mind, regular veterinary check up and routine preventative healthcare your dogs will have their best chance to live long and happy lives.

Hello there! The average age of dogs, in general, is 8-12 years. This can vary greatly depending on the dog's breed, size, and medical conditions. Larger breed dogs, for example, tend to have shorter lifespans as their size takes a bigger toll on their bones and joints. Popular purebred dogs, like labs, boxers, and golden retrievers, also have a higher incidence of certain conditions and types of cancers which may shorten their lifespan. There are so many factors that determine how long a dog will live - your vet can give you a better idea of your dog's estimated lifespan as he or she knows Bruno's personal medical history. The oldest dog I've ever encountered was 21 years old, so there's nothing that says a dog can't live a healthy life past 10 years old. I hope this helps! :)

Thank you for submitting your question regarding Copper. I would suspect that he is mixed with another breed. That is very large for a Labrador. Most male labs weight between 65-85 pounds at an ideal weight. Some will be bigger and some smaller, but is a pretty consistent average. If he is mixed with a larger or giant breed dog, I would suspect his life span to be closer to those breeds. Most giant breed dogs live 8-10 years. You can do an at home DNA test though if you are interested. I hope this information helps!

This is an impossibel question to answer, but small breed dogs, especially crossbreeds can live easily up to 15years in many cases. I recommend you discuss his diet with a trained nutritionist, particularly as he ages his nutritional requirements begin to change and he may need additional supplementation and altered protein levels - find below a useful link for a support service for home-prepared diets http://vetnutrition.tufts.edu/about-home-cooked-diets-for-pets/

Thank you for using Petco Pet Education Center, formerly Petcoach! Congratulations on your (potential) new addition! Small dogs can live up to 15 years of age, with some dogs living up to 18 or even 20. It truly depends on any underlying health conditions and how they are managed. In general, mixed breed dogs tend to be somewhat less susceptible to hereditary conditions. However, maltese can be predisposed to heart conditions such as valve abnormalities, ocular conditions such as glaucoma, and allergies. Terriers are a very broad category of breeds, but typically have the same predispositions. Please note that just because a dog is predisposed to something, does not mean that it will have the condition at any point in life. I hope this helps and am happy to answer any other questions you may have!

Unfortunately, once all permanent teeth have erupted (generally around 6-7 months of age), there is no way to definitively determine a dog's age. The best that you can do is closely examine all teeth for any evidence of tartar or dental staining. While trace amounts of tartar and staining may be present by 18 months of age, more significant tartar accumulation would be highly unlikely. If the seller has any previous vet records or vaccine certificates, these would also help to prove her age. I understand your concern about lifespan as well. As a larger breed, German Shepherds generally live 9-11 years, but in my opinion, the quality of that life and time together is even more important than the quantity. :-)
