I know they’re not small and convincing the ladies to accept them will be difficult but do mastiffs make for good watch/guard dogs? When I was a teenager a buddy had one. The dog was huge and when I first came over to his house, the dog barked loudly, cornered me, and wouldn’t let me move until his owner came in and reprimanded him. I was, needless to say, impressed.
Yes and no. The sterotypical mastiff, the English Mastiff, has muscle mass second to none. For generations generic mastiff types were bred as dogs of war and guard dogs. However, for the past 100-200 years they have had their agression bred out of them. Now, they aren't as 'agressionless' as say a Golden Retreiver, but it is definately less than you will find in a Dobie or Rottie. This can of course be enhanced with training. However, most find that Mastiff to not take very well to shutzhund. Even still, there are plenty of reports of mastiffs just seeing beyond the sport and realize it is just a game, yet become entirely different dogs when a real threat appears.
I've also heard the story of a shutzhund mastiff washout that was home alone when a burglar broke in...or more specifically, broke the glass side-window ajacent to the door handle, When he reached inside to manually open the lock, the Mastiff grabbed the burglar's hand in his mouth...then sat down. Family returned came in through the back door (close to the garage) went 'where's rover?' looked around, walked into front parlor, and there sat the mastiff, burglar hand in mouth, who looked over at them and started thumping his tail. They called police. Dog did NOT want to let go, family took some effort convincing him to do so. Whenever the burglar would twitch or make a sound the dog would emit a terrible growl. Burglar ended up with teeth imprints on his hand but his skin wasn't even broken.
Mastiffs have been used to add size to a LOT of breeds. Rotties get there size from mastiffs, same with the above mentioned Fila's (basically take a fast running agressive coonhound and cross with a mastiff for size)
A fila is a not a dog I would want to keep if I lived in the city or around other people. They are good at their jobs just like Malinois but both dogs are for a select crowd IMO
I can see that definately with a Fila, and also with some of the eastern asian Flock Guardian types. However, not the Malinos. Yes, most people's experience with them are through their roll as police dogs. Remember, they are basically German Shepards with a little less size, straight backs, and less hip problems. To be fair, in the 1940-70s, German Shepard Dogs (GSDs) were demonized as bloodthirsty attack monsters the way Dobies, Rotts, and Pitbulls today are. Truth is, they are herding dogs with big drive, smart, and great at taking instructions. This is why they make good police dog. If anything, think of them like Border Collies, just with a little less GO GO GO. They are best with a job, even if that is chasing frisbees (on a very regular basis) or competitive flyball or agility competitions.
People have mentioned their dogs being pushovers etc, or just not noticing the owner when the owner comes home late at night, etc.
Dogs don't understand logic, and the live in the moment, and they live for the pack. A dog is VERY good at sensing a person's underlying emotional state. Don't discount a dog that is 'likely to lick you to death' simply because they great peaceful guests with slobbery kisses (heck this may well be the dog trying to tell the guest that said guest is below dog in pecking order of the household...unless he is licking at the face, then the dog is saying "i am below you")
This counts both ways. Just because someone claims their dog is nothing but a big push-over, you as a stranger they may alert on and treat entirely different.
The only dog I'd worry about would be the dog that when it sees a stranger coming stays silent and goes into hiding.
I notice this topic is about 3 months old, so the poster will probably have gotten his dog by now, but it sounds like you want an 'alarm dog' and there are a ton of small breeds that are just fine for that. Note, they aren't necessarily better than larger breeds, it's just that us humans seem to be more tollerant of a small dog running hither and yon yapping up a storm, or growling fiercely at the mailman. Many humans laugh and think it is cute because the dog is small. News Flash! Dogs aren't logical, they aren't very aware of their own size, and 99.99% of their brain is still wired in basic 'wolf'. If people have a German Shepard or Black Lab or whatever that goes bonkers, runs around from window to window and barks like crazy it is a MUCH bigger commotion, and we tend to displine them to stop that. Same with bigger dogs growling, people are much more likely to give them commands to stop, or even seek professional traning if the Dobie does it, but not the Maltese.
