4 yr old blind Shar-Pei with phobia of water and anxiety issues?

Well the best thing is to try and stay positive for her. She is blind so she relies on her other senses the main one being she is able to sense what you feel thus causing her to become more agitated. Try not letting your issues of scaring her or worrying about her or fussing over her get in the way and affect your actions, reactions and overall decisions. When your dog has a traumatic experience and then later develops issues mentally caused by the past situation it too also affects you and affects how you attempt to help her overcome her issues. Fussing over her while she is near water only will increase her anxiety and fear as she is sensing that your uneasy. To you a tough love approach is not fair because it is not her fault and she should know that she is ok. As far as your dog is concerned by you having no rules or any discipline makes her feel more anxious. Dogs live in packs and within each pack is a leader. You dog has no leader therefore her symptoms become more extensive and more severe. Im not saying to throw your dog in the water and to to be cruel what I am saying to be stern and be the pack leader and the dominant species. Treats work use her sense of smell to follow you and once in the bathroom treat her, once she does something else good, treat her and so on and son. It wont work the first time but eventually it will work. She will associate treats with listening to you and that being the reward for her great effort. Rewards always work to train a dog.even a traumatized one. The rash and obsessive licking does sound like Obsessive compulsive disorder and again just like us, time will be the only cure. Your way of thought and over caring nature needs to change around her she needs to know that you are the boss. Eventually if things go right most of the symptoms should have gone and a happier healthier and less fearful dog will be the biggest change. Again like I said it's hard really hard and it does take time but just keep your vet advised on what you are doing and how she is progressing. I wish you all the luck and I hope it all goes to plan. Good luck.
