We do the across border thing all the time. Pretty simple if you remember a few things. The booze issue has been covered pretty well.
For dogs make sure the rabies shots are up to date and have the paperwork with you to show such if asked and there will be no issues. Dog food make sure they are original unopened packages and there will be no problem. If you use a special food bring enough to last or if a regular shelf brand you should be able to buy up here.
Leave fresh fruits out of your fridge. Not all but most are regulated and just buy them when you get there. Leave potatoes at home too as there are lots of regulations there and most likely will get confiscated.
