Is it fine to keep my dog under dog care taking organization when I am away ?

You need to board them. I have a cat and if I board her it would cost me $20 a day....let's see now, if that were the same case with dogs then it would cost you maybe $420 or more. Pets will get lonesome but at some places their being together would help.
Having someone take care of them at home would probably cost you $10 an hour, one of them could run away, walking them might cause an insurance problem (do you have your dogs insured to the hilt) and there are cuyotes and other wild animals out there looking for food these days, and so you're really giving a dog watcher a LOT of responsibility. I'd say make sure wherever you take them that they're a reputable place, been there a long time, licensed, etc.

I CHECK THE CENTRE'S Quality first in past reviews of other past people who left their dog there.

They would be happier if they were at home. Just ask someone to come walk them three times a day & feed twice a day.

If you do board them make sure they have the kennel cough shot & that they are utd with all their shots.

Yes, that's a good route. Make sure you pick a place that has good ratings.

Yep
