Summery weather is great for a number of reasons, but the increase in bugs swarming about isn't one of them.
Ticks are unfortunately one of the insects that are more common during the warmer months, and the tiny pests like to lurk in long grasses before they attach themselves to humans or dogs.
Most of the time they're harmless, but in some cases, ticks can carry Lyme disease which they can pass on to whoever or whatever they've bitten.
