Do dogs keep rats away?

Can a pet dog help repel rats? Unfortunately, not really. It's true that several species of terriers were specifically bred to catch burrowing rodents, and even rats. Examples include the Scottish Terrier and the Jack Russell Terrier. These dogs are actually good at catching rats, if given an environment to do so. But the problem is that you probably have rats inside your house, in the attic or walls. Your dog is of no help there, because the rats are safe in such enclosed spaces. You might consider letting your dog loose in the attic, but the rats will easily get away and go down the walls or other gaps where the dogs can't get them. In addition, the insulation might not be good for your dog.

Good rat dogs like the Scottish Terrier and the Jack Russell Terrier can catch rats in the outdoors. Yes, dogs can kill rats. So if you have such dogs outside, they may catch a rat or two and keep the population down. But rats breed very quickly, and there's no way your dog can make a meaningful dent in the population.

Cats are superior to dogs when it comes to catching rats. But even several pet cats that are skilled hunters will not guarantee to solve a problem with rats in your house. I have been to many rat jobs at households that have many cats, and outdoor cats. Rats are very good survivors, and when they have a house to live in, cats and dogs can't solve the problem.

Do dogs keep rats and mice away?

Hard to think of dogs chasing rats and mice. Right? Well, most people do not relate rat control with dogs. However, you will be surprised to learn that dogs too are as good and fierce with rat and mice control as cats are.

Why would you use a dog instead of a cat?
  • While dogs are territorial, cats sometimes have an attitude that seems to suggest that they really do not care what is going on around them. This in essence means if your cat doesn't feel like running around, it simply will not.
  • As cats get older, they tend to get less inclined to heavy work and running around, preferring to sleep as long as is possible. Dogs on the other hand, will keep active until they simply can no longer do anything about it.
  • Because dogs are loyal, they tend to want to please their owners as much as is possible. This means if you have trained your dog to catch mice and rats in your home, then you are guaranteed to get the results you are looking for.
What type of a dog do you need to catch rats and mice?

The truth is any dog can keep rats and mice away. However, how you train them is what determines the final outcome. There isn't a type of a dog that best fits this job; however, you may need to consider a smaller dog that can go into those hard to reach areas where families of rats and mice are hiding hoping they never get caught.

A dog that has been in an animal shelter may desperately want attention and love. These dogs may therefore be easier to train than the typical house trained dog that has had shelter all its life.

A dog that is specifically trained to keep rodents away will also do much better than one that is not trained. Therefore, you must consider training your dog from an early age for this purpose.

How do they keep the rats away?
  • Their size intimidates the rats, not to mention the fact that they too can turn predator to rats and mice.
  • Their barking can be distressing to rats. Eventually, this 'bugging' causes the rats or mice to simply move homes.
Final thought
Your dogs will keep rats away; all you need to do is train them to do so. When they know their job well, dogs can outdo the best cat 'mousers'.

Email from reader, with dog
There has been either mice or rats or some other rodent in my attic for quite a few months. I live with my son (teenager) who is too scared to go up there I went up approx october after hearing scurrying whilst in bed I didn't see anything. Not even mouse poops. I called the local authority who came out. Left poison in small dishes. Note they don't even go up for health and safety reasons. Just push open the attic access lid. Returned 2 weeks later. Poison had been eaten and lots of mouse droppings he said by them so filled it up again My brother got up there after me ringing him as now I was worried. He put some mouse traps up there. About 4 different types. Came back a wEek later. Nothing in the traps (baited) and I could still here scurrying. I did say I heard specific scratching in one area. There was a dead baby bird. Seemed eaten half eaten. Which he removed. He started to clear it out and an old bag had some bits in the bottom (like chewed). And an extremely strong pee smell and lots of poops. we cleared everything out. This was early december. Teddies. Cards. Cases. Clothes. Anything mice could bury into. Its 3am here now. 4 months later I am hearing something running above my head. All the authority has done is put poison down it keeps getting eaten. My brother has put up more traps but nothing in them. Outside last week. A substantial amount of earth was pushed away under the shed. After seeing it the authority said it was rats. Not mice and that's possibly what might be in the attic. We bought a dog last year. Summertime. Kept outside overnight. Foolishly my husband was leaving it some food out. Also. In my shed. A very strong smell of pee and huge amount od droppings. Further investigation showed they had got into an outside pond fish food supply (chewed thru a bag) as I noticed the droppings were orange. The same colour. This I cleared out totally. Throwing out any cardboard boxes etc. And put traps in. I check them daily. Nothing in them. The dog barks periodically. I've not told my husband never to leave food for the dog in case that was the food supply and he doesn't. It doesn't seem to bark early hours now either. Do dogs kill rats? I have lived here 20 years and never ever seen a mouse or rat in my property. I am extremely clean and clutter free. My garbage is kept inside plastic bins and collected on a weekly basis. I've never seen any mouse droppings or mice inside the house. But the fact that the council have now confirmed rats definitely under the shed is upsetting me and I don't have funds to call an ex terminator who are really expensive here. What is my next step. Please help. My husband is disabled and can't get in the attic. My brother lives a way away and comes once a week. He said it may be a squirrel in my attic. Am now going to purchase rat traps and a squirrel trap. Can rats be caught in a squirrel trap. I am too scared to now get up there!!! Please help!


Although I wrote this site with rats in mind, such as the Roof Rat and Norway Rat, the same principles apply to other rodents, such as the house mouse. Mice behave very similarly to rats, they're just smaller. Do dogs kill mice? Yes, a dog can kill a mouse. But same as with rats, can dogs keep mice away? Not very well, and especially not if mice are inside a building, and inside the attic and walls.
