According to 75% of our Sniffspot community, Mastiffs are not a great first-time dog. This comes from their protective nature and large size. Mastiff owners say it best:
- We haven't had any challenges at all in her almost 4 years but I think size could be a challenge for some. Ours instinctively knows to be gentle around kids but has stepped on some toes accidentally and that does hurt little feet. (Laura)

Advice for Mastiff Owners
Luckily, our Sniffspot community is full of experienced, trustworthy English Mastiff owners. These Mastiff breed owners share the most essential dog breed tips and advice for prospective or new dog owners:
Start training them early.
- Training and socializing - it never ends. Get started early and do it often. This breed needs a job and structure. It's a lot of work if you aren't committed to putting the time in a Cane Corso isn't for you. (FB)
- Make sure you're ready to handle a dog of this size. (SJ)
Make sure you're ready to handle a dog of this size.
- If others are considering this breed definitely consider the size of these dogs as well as training commitment up front. This breed is also a guardian protection breed, their minds are built to be skeptical of new people and loyal to you. Not a dog that is going to be happy-go-lucky around everyone. (LW)
- They need to be with their people a lot of the time, their size alone = $$ food, vet, care, etc. be prepared financially. But be prepared for a best friend for life. Incredibly loyal and affectionate - make a great family pet with a calm demeanor. Very sweet when properly socialized. (Alana)
Many owners say this dog is picky.
- You will sweep up more dog hair than you could ever imagine; you need to have somewhere cold for him to sleep at night; his food requirements change daily (one day wants frozen beef and the next day cooked chicken; doesn’t like the same thing two days in a row). (Karyn)
- You need a lot of time, patience, and money (because many medications are by weight). You also have to be prepared for the heartbreak of them not living as long as other breeds. They're not ""stubborn""; you have to understand and work with their particular motivations and breeds are not a monolith. The dogs within a breed are still individuals with preferences. (Sarah )
Have the right lifestyle for them.
- You need extra time for training consistently, good for families with PROPER socialization, and make sure your dog does not think he is the alpha of the house (the owner is). (MiKayla )
- You need to know what you’re signing up for and understand it is a lifestyle breed that needs a lot of training, exercise, and mental stimulation. They also feel very unhappy being left alone for long periods. They want to be with their family. (S. P)
