After I posted my first reply, I thought of a couple of other things to mention.
You asked about dog food
. Our Toby weighs about 60 pounds. He eats dry Pedigree - about a 22 lb. bag each month. We left on Cruise
#3 with 7, 22 lb. bags of Pedigree, each one bagged in a tall kitchen trash bag for extra waterproofing. That calculates out to 154 pounds of dog food, but even though we saw it from time to time in grocery stores, who wants to schlep it around in a dinghy
, or perhaps waste time reprovisioning because you are low on dog food? Bags were stored in the bathtub, and the last bag was as crunchy as the first (attested to by Toby himself).
We did have a dog once, who lived on rice and ground meat. We bought broken rice at the bottom of the barrel (living in Singapore
at the time), which came complete with bugs, and was about half the price
of regular rice. And saw meat, which is the meat shavings from the butchers floor. We cooked it up - gave it a fancy title - "Beef and Bug Rice" and she lived on it and thrived. A more civilized version of canned chicken, vegetables and rice might be ok, if you trained your dog to like it first. However, large quantities of rice are heavy as well, so it might be a fairly even trade-off with dog food.
Toby gets all the annual shots before we leave, and we don't take any other shot medication with us. But we do take the monthly flea and heartworm medication for as long as we plan to be gone, plus a month, and plenty of topical and oral medications recommended by our vet. Even if your dog doesn't take flea and heartworm routinely now, he/she will probably be coming in contact with local and island dogs who receive little or no veterinary care - so a little prevention is a good thing.
The horse leg wrap from Tractor Supply type stores is a good thing to take along. It is like a thin adhesive
bandage that sticks to itself. It is comfortable enough, and we have used it on Toby (he is a frisbee dog and occasionally sprains something or gets gimpy), he has not tried to chew it off. Reasonably priced and comes in many different colors and widths. It's in our pet first aid kit, but I keep thinking that it would be a good item for our human kit as well.
And last but not least, a tetanus shot for the human crew is a good thing to have before you leave. George was bitten by a potcake (stray Bahamian dog) in George Town, Great Exuma, and was glad his shot was up to date.
Sorry to ramble on so much, but hope this helps.
