Use advocate it covers heaps of the nasties including fleas at both stages, many worms,mites,lice & heart worm.
I have had dogs get sick on capstar but have heard great results from others using it.
I find although a little exspensive to buy when you work out the cost of doing everything the Advocate dose it's actully a very fair price.
I find it works heaps & heaps better tahn frontline although I do use the frontline spray on sleeping areas & bedding etc.
Dose your Dalmation xbreed have spots & what colours is he?
