I have a 60inch thorn smart TVs and my dog chewed the remote can I download a remote and if so where do I go?

I'm leaving the link here for you to order a replacement https://support.vizio.com/s/article/How-to-Order-a-Replacement-Remote?language=en_US

I would repair the remote. Remotes can be very easy to resolve issues with as long as they are not physically damaged(dog chewing on them etc). Otherwise your best bet is calling the company for a new one or trying a multibrand remote for ac units like the Tado Smart thermostat.

To play 1080p movie, just do it. No further move needed, cuz most smart TVs have no problem in playing back 1080p full hd videos. As for 4k Ultra hd video, you'd better downscale it to 1080p if you're not sure about your tv resolution.

How come dogs chew our things instead of their toys? As the first answer suggests search the manufacturer's website. If its an old remote then try Ebay. Sometimes a local pawn shop has a box of remotes that you can look through. In the meantime you can always buy a generic universal remote that you can program to work with your TV.

Dog boots offer many benefits:

• They protect the dog's paws from different materials like glass, grass horns, and stones.
• They protect the dog's paws from both the heat and the cold.
• They are very beneficial for senior dogs who have more sensitive paws.
• They protect from the slippery floor of the house.

Dog chewed my .... A first for FixYa.

In the USA look at; www.remotes.com
For the original remote. That should solve part of your problem. What to do about the dog is another story.

acquire universal remote.
acquire exact replacement from mfg if avail.

no alternative if your remote is destroyed.
based on your need to access menus with it.

then hope your dog develops a taste for something else.

to that, my dogs chew bully sticks. it satisfies their need to chew. which is a really big drive. and they cost a bit, but last a long time.
and its cheaper than replacing remotes and furniture, shoes and other things.
and your dog will be extremely happy.
costc has started carrying them.
most pet stores carry them.
they are also known as pizzle.
you really don't want to know more about them.
they will keep your dog happy when otherwise bored.

good luck
have a happy dog.
