Our 7 month old puppy has just been castrated. All went well with no problems. The first night my husband slept downstairs with him as he was unsettled. The following day he was back to his normal self so that night husband had an early night and I stayed up to put him to bed, (he's crate trained). As my husband left our pup started crying and panting and got distressed. I distracted him with toys and play with some success. After toileting he went in his crate and started crying and didn't let up, which is so unusual for him. In the end I had to wake up my husband, who was not happy, to passify him. My husband is at home with him most of the time. My question is, where do we go from here? I don't want this behaviour to become habit forming. Please has anyone got any advice on how i can proceed forward?
