There is a pet food store near Certified. Also some grocery stores carry dog food.
This is from a friend in Aruba.....
I know they have Pedigree - canned and dry, Alpo, and some Dutch Brands at Ling and Sons. If you are into Organic Dry food for your dog, they have a special brand at the Pet Store behind Hong King.
You can also pick up Eukanuba, at the Contreras Vet's Office in Noord - both canned and dry.
The store behind Certified has Royal Canine and Eagle. Best bet is to go to the vet in Noord. It is on the road where Tomato Charlies is on the circle. If you need better directions - just let me know. I'll have to have my hubby post because directions aren't my "thing"
