My dogs are chewing everything in the house one is 16 Monty's old the other 6 but it seems the older one is chewing more. From walls to controllers. What is the cause n how do I prevent without abuse
First of all, I suggest with questions such as these - to seek a medical professional, because here on the forum we're not trained physicians or veterinarians and so all we can give is our own perspective. So I suggest calling a vet first and foremost if this is a persistent problem.
From my perspective, it could be something with their teeth or mouths, either a problem with the teeth or gums themselves - like the chewing supports with an 'itch' or ache in the mouth - or sometimes there's also vitamin deficiencies that can show in animals through them chewing on stuff. Another possibility is that they simply enjoy it. lol.
Abusing animals in an attempt to 'discipline' them doesn't work. So please don't resort to abuse.
The best possible way to deal with such problems is to 1) make sure there isn't a physical problem with the animal. 2) To prevent important things from being chewed on by placing them out of reach so the animal can't get to them. There are also natural sprays that one can get in pet shops that will give a taste the animal doesn't enjoy to the item if needed, which could be useful for example on walls or other things you can't place out of reach.
Let us know how it goes!
