No. This is not an acceptable practice. Chaining or caging up your pet constantly is inhumane; your pet can become restless, agitated, distrustful, physically ill or develop psychological problems.
Caution to pet owners
An owner tied up his dog on a chain. While he was out, the dog got entangled in it thereby restricting its movement. When the SPCA responded to the call along with the police, the dog was already dead.
A post mortem revealed that the dog had died of heatstroke, unable to seek shade because of the chain restricting him.
Many pet owners tie their dogs up – the number of reports received monthly by SPCA are testament to this. Unfortunately, they do not think of the serious consequences which can occur as a result.
Dogs are not prisoners…if you really need to chain your dog, Please don’t even think of keeping pets.
There is nothing wrong with tying your dog up, as long as the chain allows plenty of space for the dog to walk, the dog can reach fresh water and food, the chain can twist which stops the chain from tangling, and the dog can reach appropriate shelter, Also clip the chain onto a collar don’t wrap the chain around the dogs neck. My dog is kept chained while we are not out there with him, I don’t see how this is worse than people who cage their dogs when they go to work. If you want to stop something stop inhumane cages.
Also you must still take your dog for a walk or run and go out and play with them every day
