Usain do you think the lint roller would work on a hairy spaniel? And does it not risk pulling the body of a tick away leaving the head embedded, which causes higher risk of infection in the dog?
Round here vets haven't been recommending tick treatments, until very recently, because they were very uncommon. My vet started stocking one type of tick treatment late last year, as there was apparently an increase in the area.
Both my dogs appear to have picked up ticks in our garden! Dog1 got one on his head recently and bathing very hairy spaniel dog2 yesterday evening, I found 3 of them on his ear (still very, very small so presumably very recently attached) and he hadn't been out on a walk for 36hrs, so I think they had come from my garden. (they'd missed the walk the day before due to sick child unfortunately, but did go late last night when mom was able to come over to stay in house with DC whilst I took them out).
I'm going to swap on to the tick killing deflea and worming program now.
Re worm count it can't check for one type of worm can it? I can't remember the worm name but I'm sure there was one that can't be tested for. Also dogs don't shed worms all the time, so can have a burden without it being picked up in worm counts.
Re vaccinations I don't know of a single vet who does the ones recommend for booster every 3-4years more often than that.
