I’d pack very light. I would assume my destination would have a place to buy what I need. I would factor all that into the price. For instance if I went on a trip to visit India I would take only my purse with my passport and tickets, etc., in addition to my regular purse stuff. Then once I got to my nice big hotel I'd shop for any needed toiletries and clothing. Then when it was time to come home I'd discard or otherwise leave everything behind.
Those creatures look like mite or flea bitten mangy coyotes to me. If I had a mysterious animal I would seek to identify it if it were still alive. If it were dead I would try to keep the body and not tell anyone about it because I would want to wait and see what I could learn about it myself.
That's an interesting philosophy on travel. I've always gone on vacations where there wasn't much shopping, so I tend to pack very heavily.
It will be interesting to see whether we hear anything more about those animals. If they turn out to be coyotes, you will have nailed it first.
