Veterinary logos are mainly used for representing companies providing such services. These include both veterinary clinics and hospitals. They target those people who are taking care of animals and want them to stay in the best of health. These are not only pet owners, but also farmers who want to maintain the health and well-being of their livestock. They hence need a clear-cut logo that tells them about a place where their animals can be treated and given medical assistance.
The symbols of veterinary logos could include a shape that resembles an animal, usually a common one like a cat, dog, or both. Some bandages or hearts added to these shapes could signify the types of services provided. If the veterinary organization offers services for larger farm animals, it might want to include the profile of a cow or sheep as well. The colors used here would be according to the animal that's used, though blue shades may give the effect of a sanitary medical environment. Hence, a blue-shaded cat with a bandage on one ear would create a striking effect for a veterinary clinic.
Your brand message and brand styling should also be apparent in veterinary logos. If you're a serious animal hospital, you should probably avoid logos that include cartoon animals or similar elements. If you're a small family business running a pet daycare, though, there's no harm in using cartoon animals that are smiling or holding heart shapes. However, generic animal shapes are not recommended, as they don't specify what the logo represents.
If you want an effective and attractive logo for your veterinary organization, you should look into hiring the services of a creative logo designer. This step would make sure that you have a logo which stands out and attracts your target audience in a relevant and meaningful fashion.
