I was in the middle of replying to some ones thread when my computer crashed and I lost everything and now can't find the original thread so thought I would start again.
I live in a very high paralysis tick area. We are even removing them from ourselves on occasion.
For our long coated setter the best prevention has been the Preventix Tick Collar. The fact that it is also the most economical is just a bonus.
But nothing replaces the hands on check by getting fingers down thru the coat and massaging along the skin. The most prevalent place for ticks to attach are the head, neck and shoulder areas but they can be everywhere.
The liquid applications that go on the back of the neck need to be done every two weeks for ticks, not monthly and my long haired dog has gotten several ticks while having these products. It takes 3 days for the tick to die on the dog so if your dog gets multiple ticks the dog can still get very sick/die before all the ticks die.
The collar must be left on at all times, never removed. When you wash the dog remember that it will not have cover for 24 hours.
If you do use the liquid applications for a large dog it is best to put it on the neck, half way down the back and above the tail so that it can spread to all areas of the dog (using the same application).
If you see your dog scratch, you check.
Remove any ticks you see immediately, don't wait, even if you don't get the head out if you squash the body it still dies, the possible and I say possible infection your dog MAY get from the head being left in will be nothing to the tick staying in a minute longer than it has too. Get the head out later.
Don't fiddle with the tick while it's in the dogs body as it makes the tick inject more poison, I know because I've felt them on myself. So I use my thumb nail and forefinger to remove them then and there rather than go search for the tweezers and then have to re-find the tick.
If the tick is very small your dog will be ok but if you are worried go to the vet (we've lived in this area for a long time now and gotten used to what requires a vet and what doesn't), if you see any symptoms that your dog is unwell go immediately to the vet, signs of paralysis tick poisoning are weakness in legs and a change in bark either or both.
If you find one tick keep looking.
Keep grass and shrubs clear, ticks like to wait in long grass and bush for a suitable host to walk by and then attach.
Hope this helps.
