Both breeds are suitable for the city and are also quite easy to care for. Both the Bully and the Chihuahua are brachycephalic breeds. This can pose some problems.
The bulldog often has a sensitive stomach, prone to flatulence, snoring, and breathing problems. Especially specimens with very flat noses.
A Bully is significantly heavier than a Chihuahua, grows larger, and needs more food. The life expectancy of the French bulldog is much shorter (10-12 years). Her character is affable, patient, and playful. It is suitable for beginners.
Please do not decide based on appearance alone, but familiarize yourself with the requirements, special features, and character of the respective breed. Are there any special problems (sensitive stomach, hunting instinct, behavior) or diseases within the breed? Which breed suits you and your lifestyle better?
