Yes, those are ticks. Here we get a lot, sheep and deer ticks get onto the dogs (and occasionally onto people.
There are various ways of removing them. When ticks bite they make a quarter turn clockwise so if you are going to pick them off, twist anti clockwise and then a sharp tug - works 90% of the time. Another way is to get a cotton wool bud and soak it in alcohol - any spirit (whisky, gin , vodka etc) meths or a stinging aftershave which is high in alcohol (Old Spice for instance). Squeeze the soaked cotton wool bud immediately on thr mouth prts of the tick - gives up in about ten seconds usually. Final method (and not to be used if alcohol has been tried) is light a match and apply to the rear end of the tick - one second usually gets it off. Better for humans than dogs because of fur problems. If all else fails, got to the vet - if for human treatment, take an empty box and pretend you have a mouse. Doctors have no idea what to do, usually.
Ticks are serious both for dogs and humans - Lyme's disease is fatal.
Frontline (preventative) sorts out ticks in the main but some dogs react against it and there can be problems if you also have a cat, check with your vet.
