No, they wear off naturally against the ground. If the dog doesn't get enough exercise on rough ground, they will need to be trimmed by a human.
Walking the dog on pavement may wear the claws down so you'll never need to trim them. If you hear the claws clicking on the floor or the pavement, you probably ought to trim them back. A good target length for a medium size dog is about a quarter inch. Cutting them too close will injure the dog. One thing to bear in mind is that if you don't at least go through the motions of trimming the claws about once a week--followed by a treat, to get it used to it, your dog may fight you when you really need to trim the claws. Some dogs get really unnerved when it comes to having their claws trimmed.
Yes, that's why they have claws to kill and teeth to chew and snap. Cats and dogs can catch mice, however cats are naturally better at it than dogs. Sorry Fido. :0)
Don't, there is no need to trim a cats claws.
The claws help them climb and the teeth help them chew.
Dogs have sharp teeth which helps them chew on hard things.
Yes, if you trim them off your toe first.
No, dog's claws are not retractable.
if they have front OR back dewclaws they have 18 claws if they have front AND back dew claws they have 20 and if they have no dew claws then 16 claws.same goes for large dogs
Yes, pig ears can be good for dogs to chew. They clean dogs teeth. In addition, they allow dogs to chew and eat something that they like and it gives them something non-destructive to do.
Dogs chew all your stuff because they think it is a fun game. If you give a dog a chew toy and teach them that is what they should chew on, they are more likely to chew on their toy then your stuff.
They have five claws per foot!
No, as all dogs have atleast two dew claws when they are born (unless they are removed).
