Hi Lyn, well hehe that is a problem
When you went to the vet did they do any tests??? I have a few ideas, first to mind is bladder or uti, but since you have been to the vet for that its probably not. so another thing is what someone else posted here, the shampoo, or coat conditioner spray or what have you, you use. Just like two legged kids, dogs can get infections from getting schampoo in their privat parts, and it can burn, sting and itch. Also yeast infection.....
. That burns and itches like crazy. the yeast they can take a little scrape test and see if it is.
Things you could do to try and help him, is to rinse his peepee with luke warm water, and kinda rinse out wat may be "in there"
Also give him yoghurt could help, it regulates the ph, and helps the urine be a healthy ph.
Our Galahad is doing some serious licking too, but never chewing, thank god hehe, and absolutely no need to feel silly about posting questions like this, thats what this board is soooo good for. no questions are silly..... Please let us know how he is doing, and how things turn out, I will absolutely keep my fingers (my dogs keep their paws) crossed, that he will still have a little winky when the problem is solved
