How old is your dog in human years? Multiplying your dog’s age by seven is easy, but isn’t very accurate.

This carefully graded system piles the equivalent human years onto a dog’s life more quickly during the dog’s rapid growth to maturity.

If we think like a dog, here’s how a dog’s age compares to a human’s age! There may be some differences between breeds, but this should give you a good sense of where your dog is in the development/aging process.

Is it too early to take the puppy home?

Hi. My family and I are going to be getting a new puppy on Saturday. The gentleman that has been a breeder for several years and has great reviews and extremely happy customers.
My concern is that pur puppy was born on January 4th, 2018. The post/ad said that the puppies would be ready for pick up on March 1st. However when I talked to the gentlemen and asked if he still had any male puppies left and he said yes. He said he's asking for a $100 nonrefundable deposit. So I told him that we live 4 to 5 hours away from him and wouldn't be able to drop off the deposit until February 17th as it is a 10 hour round trip. So he said that when we come up on February 17th that we could bring the full amount for the puppy and we could bring him home that day. Even though they have had all deworming meds, 1st set of shots, & are seemed and eating puppy food and are doing well I am concerned that he may not be old enough to leave. I mean wouldn't he only be about 6 or 7 weeks old?

when to take home a puppy

If I understand correctly, on February 17, your puppy will be just 3 days past six weeks old. Ideally, the longer a pup can stay with its mom, the better, as far as developing social skills with other pups in the litter, etc. Six weeks is the minimum time when pups should be taken to their new home (unless in an emergency). Some state laws require that the pup must be at least 8 weeks old (which would be March 1 in your case, as the ad said). You might contact a local veterinarian to see about your state’s laws and whether in general there might be any concern about the timing. Ideally, if you can wait until the March 1 date for pickup, your pup might be better off in the long run.

When to take a puppy home.

Thank you so much for your quick response. I will be contacting our vet right away tomorrow morning. I wouldn't mind keeping the puppy where he is until March 1st, but it seems like for some reason the breeder feels like it will be fine. So I'll check with our vet and get her take on the situation as I Don't want to do anything to harm the puppy or it's development. Thank you again.

Weenie puppies

I have had several litters over the years, Also I curently have a litter now as well. Born on feb 2, I've always kept them about 7 & 8 weeks but the experience I've had is if mommy does not want them at all anymore there eating dry and wet food peeing and pooping,playing all on there own I don't see the harm in sending them to there forever homes before they get to attached to my surroundings when they could be bonding with there new familys

Dog years

My great dane was 9 1/2 (dog years) (54 human years) when he passed. Pretty young sounding, huh. I don't think this chart gives a true picture as to how old they are in human years, as your larger breeds have a much shorter life expectancy than your smaller breeds. As grey as my old man was, and the difficulty he was having walking he sure seemed a lot older than 54. I miss him dearly, he was a gentle giant, with a huge heart.

My dog's age is..

About 36, according to the chart, (wow, older than me!) I had him for about 3 yrs, he is a Beagle Sheltie mix, he is an adopted shelter dog. We guessed on his bday, vet says around 2 when we got him. Q. My cat is about 6 yrs old, how old would he be in ppl years?

cat years

According to many conversion charts, a 6 year old cat is thought to be about 40 years old in equivalent human aging, and would be considered to be in his prime.

What about cats? How do they

You have the terminology wrong

I don't understand why you have dog years and human years the way you do. A human year equates one year. When we use the terminology of dog year it implies the equivalent in dog years, not "human years" as you state.

dog years

We understand your point, and it can be confusing. “Dog Years” in this case is the actual dog’s age, such as would be on a veterinarian chart (tied into Gregorian calendar years). “Human Years” is the equivalent age in human years that matches the stage in development of the dog at the specified dog age (the one on the veterinarian chart). So, for example, because a dog ages faster than a human, a 1-year-old dog according to the Gregorian calendar (dog years) would be the equivalent in age and development of a 15-year-old human (human years). We’ll think about the headings and description to try to make this clearer. Thank you for your feedback! 

PUPPIES

I have a adorable new puppy her name is Bubbles. I love her so much. She is 2.5 months human years but I cant work out how old she is in dog years. Please help me. Thanks.

puppy age

Unfortunately, our chart does not cover dogs that are less than 6 months in age. Puppies mature rapidly in their first months of development; just how much will depend on the dog breed (size) and other factors. For a very rough estimate, you might use the formula: 6 months dog age/10 years human age = 2.5 months dog age/x years human age, which yields  a little over 4 years in human terms. Hope this helps–and congratulations on your new puppy!

Cats

Does the dog age chart apply to CATS too??

Cats

No it doesn't, but I sure wish they'd publish a chart that does.

cat ages

Traditionally, it was said that each year a cat lived was equivalent to having lived 7 human years (so, a cat 3 years old would be 21 years in human terms). However, this turns out to be incorrect. Cats mature faster during their first 2 years. Actually, looking at the dog chart above, it is very similar. The first 2 years of a cat’s life, it is estimated that they have matured to about 24 or 25 years of a human’s life. Then from there on, the cat develops more slowly, every year being the equivalent to about 4 years of a human. Maturity rate, aging, and lifespan of an individual cat will depend on environment, health, breed, etc., but this is a general guideline.

Dog age

I have a female rat terrier that is 17/79 1\2 years old. Very loyal and loving dog. My new puppy is 4mths old so she isn't quite 15 human years, my Res Boston Terrier is 8 dogs years & 52 human years. All are family dogs. Love them all.

I've also seen where a pup's first year was equivalent to 15 years old, and subsequent years equaled 7 years...

Horses

how do horses age?

horse ages

The age of a horse equivalent to human age will vary upon many factors, such as breed, etc. In general, though, it is thought that horses age about 6.5 years for each human year until age 4, when it is a young adult of about 20 in human years. After age 4, they age about 2.5 years for every human year.

Like my dog throws up idk how

Like my dog throws up idk how long he is going to live how do u know when your dog going to die

Mia Harris-how do you know when your dog is going to die

I realize that it's been almost 2yrs since you posted that your dog was throwing up & you didn't know how much longer he was going to live...I hope you don't mind me asking, but were you ever able to get him to your Vet's office? Did he stop throwing up? If he has passed on, I am VERY sorry for your loss. I pray that he didn't suffer. Please forgive me if I open old wounds. I was merely trying to educate myself. As I too have a fur-son who seems to have a stomach issue. He's always eating grass. But not just any grass...he seeks out certain weeds & very carefully bites off the top of each stalk individually. Do you have any advice. Please & thank you.
Be blessed, Kriss VanOrnum✌☺

Dog Eating Grass

Hi Kriss,

Whatever grass your dog may be eating, there are a couple of reasons he may be doing it. He could be have stomach aches and trying to relieve the distress by attempting to vomit, eating large quantities of grass to do so. If your dog has not vomited, it could just be regular dog behavior. They explore the world around them with their mouths, eating and chewing things as they go. If vomiting does occur, take your pup to the vet right away.

Dog throwing up

My 13 year old black lab mix has a problem with throwing up. I took him to the vet and she said that he was having pancreatic problems and gave me pills which helped immediately, but then they stopped working as well. The pills are lifetime, named pannekare.
Good luck.

Throwing up

I was told by my main vet and a couple others, that most generally dogs like to eat grass just because, but they throw it up because their bodies are unable to digest it correctly

I scold my dog away from

I scold my dog away from eating grass, he vomits immediately after, but I thought I read they can get worms, that their eggs are on the grass, which gets in the dog then.
