sounds serious

well you can go to the vet and ask for "tactic" solution.tactic is very very effective. well follow the instruction careful when u apply the medication.to clean the area with tick , u have to take it dilute it 1 portion to 10 portion of water. Use those spray bottle n spray it all over the house, garden & those place which is with those stupid tick and flea. Avoid letting your dog walk near to the place u have been sprayed okay.because tactic is very strong medication. u can see those tick and flea will drop on the floor after apply this medication too. make sure clear them away,flush away !!! or u can burn it if u wanted to . anyway since u saying the anti tick/flea shampoo is effective so i think u no need apply the tactic '' on ur furkid body ..but beware if u use tactic on ur furkid body ya...because is very dangerous
if ur furkid smell or even accidentally lick it...BTW how old is ur furkid ? because furkid which is below a certain age like 3-4 month is not suitable to apply strong medication . anyway hope this help buddy . Hope u clear those stupid small vampire away ASAP . Good Luck

yea agree ,if wan to use anti flea/tick spray i feel Frontline is the best
because tactic is a strong medication and can cause dog in danger .

but if to clear away those small vampire which is climb the wall , and garden etc.....I think tactic or bayticol is recommended .
but of cuz after apply the tactic or any medication which can kill those tick/flea , better avoid furkid go to the place which is spray with tactic or bayticol ...because the smell of the medication can make people faint also
