Consider the dogs health
You may want to consider the health of your dogs before planning to bring them to the island. If they are accustomed to hot climates there should be little problem. However, if they are heavy coated and originate from a temperate zone the change to the Dominican climate may be too much stress for them.
Another item you should contemplate is to check way ahead with the air service, there may be an embargo on the transport of live animals to the D.R. in effect during the summer months due to the excessive heat. The air cargo holds become ovens. If they due allow transport, it will be only for direct non-stops flights only. Don't wait until the last minute, get the full information now from the airline.
Escott does have it right. I wouldn't rent a place to you. I recommend you leave the dogs to someone you trust at home and take a vacation away from the kids. Regards,PJT
