I assume you want the Brand Name for the product name, I am not in touch with the Horse or OK culture and probably can't make a good guess.
There are sites with tools that help you come up with fictitious names, including: wordlab.com, naming.net, wordoid.com, lingzini.com, namestation.com, some of these tools look up the domain name availability as you go.
If you find an available .com name, there's a high probably that it' not a trademarked name.
You can feed Horse or Equine into wordlab and it will invent a series of new words based on it.
Fresh horse
Horseland, I like it. I hope it helps you or gives you an idea. My English is bad, but I'm not English, sorry. Good luck!
I am setting up a business and I will sell Horse things aimed at horse owners who may be struggling to afford the 'extras' for their horse, such as hoof oil and fly spray (both of which can fetch up to £20 per item- and I can get through a bottle of fly spray in a week, especially in hot weather).
All my products are between £5-£15.
I have made prototypes of my products, such as-
Show sheen
Equine massage oils
Antibacterial hoof oil
Natural fly spray (it has no chemicals in it so it is safe with no side effects).
However I am struggling to come up with an original name. I had so far
-Happy horse
-Steady Stead equestrian
-Mane Nature (Can someone make an acronym?)
But these are taken or my parents don't like the name. Help!
Can you help me out?
