I highly recommend a German Shepard.
Probably the best type of dog is a Labrador Retriever.
The best type of dog or cat food would depend upon the dog. Dry dog food is cheaper but the animals usually like wet the best.
It depends on what type of dog it is
A golden retriever is best to have :)
wolfdog
The best type would be Front Point Security. They have been rated the best on several different rating. They are a wireless security system. These are considered the safest as there are no wires to cut to disable the system.
Boxers!They have really good hearing.
The best type of dog cone for a large dog is typically a soft cone or an inflatable cone. These options are more comfortable for the dog and allow for easier movement compared to traditional hard plastic cones.
A German Shepherd , a Doberman, or a Rottweiler.
lab and Dalmation
Flannel is the best for cleaning.Fleece is what your dog will probably like best.
Depends on the security that you are talking about. If you want something just to make noise then it seem chijuajuas are very good at that. But if you want a protection dog for the family, you are looking for smarts, size, and strength. Id say German Shep, German Rotts, Pit Bulls (mine are great with my kids and very protective).
