well i tink a good thing to start with is to find out wot reason he as for losing respect as there as to be a reason for this behaviour if you start from beginning as wot i did with my welsh A as he was untrusting to new ting as i started to lounge him and did the pair bonding as it can only build the friendship that is needed between you both its like his new to you as you to him well ill be taking on a 3-4yo unbroken and he will start with tring to figuring me out as i with him and its better from the ground loose school him push away wenever he coms in range of you then wen you give him the moment he chooses to come in2 your invisable barrier then it beggins as he will stand facing you that wen you give NO eye contact wot soever then as you walk about the school if he follows then you ave joined then you repeat push away{not pysically} then repeat join up then allow him to come close rub his forehead then walk away still no eye contact and sit down anywere in the school then if he stand above you or next to you then give eye contact then rise up then you walk around rubing on/off then repeat this every day for a week then if this has helped you both then that may ave bin the problem hope tis helps let me know thanxs x
