If you ever have to trade your dog, how much money would be enough? If you are understanding enough to give him the best dog food for pitbulls, why do some 20 dollars for a tagged collar and microchip concern you? Or do you don't love him that much worth?
In case your dog gets lost, microchipping with a tagged collar can make a world of difference. They, more than anything, can guarantee that your dog will be linked back to you, and he can get home safe, given that the tag is updated with your address and phone number, as well as the Microchip company you've registered is informed about your newest address and contact information.
If you don't give your dog a collar, it screams to people that the dog has been abandoned, and there will be someone pick him up for his own interest, or give the dog to some dog shelter that may make it even more difficult to find your pup.
Also, unexpected occurrences in the house may cause the dog stress and he may feel that his leaving will give you less burden. Supposed that you've normally given him the best dry dog food, but then one day you only give him the scrap full of corn or wheat, the dog may stress out. Some dogs even run off from all these emotions inside them and eventually get lost. More sensitive dogs get frightened when there are too many people in your house at once if you hired some men to move your stuff away for relocating, or unexpected visits from strange people. When these people come in your house, they can be careless and leave the doors, and the gates open, letting your dog slip out. The same may happen when you have to go away for a long time and entrust the dog to someone you know.
