Find dog names in various categories, and lots of puppy info.

Bringing your new puppy home is such an exciting time. This new bundle of loveliness immediately becomes the center of attention. Everyone in the family will have a name that they want to call the new baby. But take a deep breath here. Naming your new puppy is a big decision and it’s important too, for many reasons. Now is not the time to cave in and let your kids choose a name. It may cause a few tears but it’s worth standing firm. Let’s go through the things to consider.

Is it a male or female?

Don’t laugh! Your seller will probably have told you the sex and you may even have chosen your puppy because of its sex. But there are lots of dogs out there who started life as George and finished up as Georgina.
If you don’t know the gender of your new puppy, here are some guidelines to help you find out. Both males and females have nipples, so that doesn’t help.
Turn your puppy over onto its back. If the puppy is male, you’ll find the scrotum almost between the back legs, just below the anus. It will be easier to find in a puppy that is over 8 weeks old as the testicles will have descended by then. If the puppy is female, you’ll see a tiny slit almost between her back legs, just under the anus.

Size does matter

Some people love to call their Doberman Tiny, or their Chihuahua Monster and that’s cute. But don’t forget that your dog will have this name for life and what seemed funny all those years ago may wear a bit thin later on. Similarly, avoid Fluffy, Cuddles, Baby or any other names that seem appropriate now - but your dog (and you!) will outgrow.
