As far as the bridge,one you glue tips down,just take those wisps of hair(not a lot) and twist them together,That bridge should hold as long as the tips hold for that period.Unless she is scratching them.If she is scratching & digging,it means the glue is on her skin,and not her hair.
always make sure the ear is clean.So before you glue,dab some alcohol on a swab,and gently clean it for residue.let it dry.
Taking the tip of the ear,you only need a small dab of glue,or you will have the berlin wall.take that dab of glue,I mean no bigger than the pencil eraser size,and place it on the tip of the ear on the inside,but make sure it is on hair...not skin.
Take that tip and fold the ear down.Looking at your puppy,you will see a tuft of hair growth on the front of the ear.Take the ear tip,and using your index finger guide that tip down in back of that tuft of hair.remeber..glue hair to hair,never skin to skin. Hold it gently for a few seconds,and you will be good to go.
I am no pro,but my gluings for the most part held for 2 weeks,some more,depending on how much the two would wrestle & play.Most times I had to remove it with detachol.
You can get detachol from your
Walmart pharmacy.Just ask your pharmacist,and they can order it.It's not something that is over the counter,as it is pricey.But it lasts along time.
Another tip,is to use a fine comb,once you put detachol on the ear with cotton,let it set a bit,and in minutes it starts to loosen glue.Keep combing,and swabbing with that cotton ball till it is all gone.
