My 18 month old large breed dog seems to be going through a huge regression. She had a second heat 3 months ago and I believe she had a phantom pregnancy (vet agreed). She was very relaxed for about a month (out of character) but the past 2 weeks her energy is overwhelming and worse than before. She has always been high energy but it's like nothing I do works, she is bouncing off of the walls even with 2/3 walks a day, playing at dog park, games/play at home. I'm just wondering if this is normal and hormonal behaviour? She's also started misbehaving, running away at times she never would have and actively ignoring me. We have put a lot of effort and time into training her and we were getting there but seems to have all gone back to puppy levels the past few weeks. Having to go back to enforced naps and keeping her on lead, thought we were past all this 😅
