There excellent, i had problems with my batteries just under a year after buying it. they changed them for me under the warrenty no problem what so ever. They are really helpfull. totaly recomend.
I use penicillin all the time for my dogs, for when they get cuts etc. It seems to work really well. Just make sure you try and keep the wound as clean as possible using hibiscrub or salt water. You may need to use more than one jab however depending on the results you get from the first jab, i normally miss a day then repeat. ( Im not sure this is the best way of treating your dogs, no doubt the vets will tell you other wise! But it had worked every time for me and i will continue to treat mine this way). All the best.
Personally i feed mine a good quality biscuit, red mills racer, occasionally mince, chicken, and mine look spot on.
Everyone has there own ideas, just try and find the best food that suits your dogs, try to avoid too much tripe
Yeah i use it alot, its great stuff, you can use it on cuts, scrapes etc or any areas that you need to keep clean. you can buy it from chemists or online. Defo reccomend
