Yes I think it's the stress, (her treats are just her canned food baked, ZD and she doesn't get more than usual really) even though good stress she has a blast wherever we go and is always at high speed which is what is so wonderful about her but apparently it doesn't do her any favors.
I think if I had to medicate her to calm her down I'd just avoid the thing all together. I'm seriously ready to stop doing photos shoots and things where people are relying on me to be there because I have cancelled on so many people this summer. It's extra stressful to worry about that and getting ready to go and will Sophie get sick and will we have to cancel or not get the job done and will an alien ship come down and land on my car with no way to get Sophie to the vet if I needed to.... (true story! Happened to me in 1726, Toronoto, Ontario, was on the front page of the paper!)
I do have some Sileo but have been afraid to try it. A few times now she's been licking and licking her girlie bits and I'm worried about vaginitis or something due to the Tylosin. argh. I am terrified of crystals and stones and want to avoid that at any cost. I may try the Sileo though as we have a few big days coming up like you say may help her not get a flare anyhow. I'm just so scared of trying new stuff on her.
We went to a ball game last night looking forward to watching relative play hanging with cousins etc, as soon as we get there some idiot had let their kid hold on to their huge lab mix who of course broke away and rushed Sophie so fast I didn't see it coming. I don't know what his intentions were but wsn't going to wait to find out so I was yelling and hitting him in the head with the legs of my folded up lawn chair (wanted to hit the kids parents in the head) so stopped it. I always have an eagle eye out for that kind of situation and can take precautions at least Sophie didn't seem to care. The kids learned a few new cuss words!
Then we were leaving and walking and again I watch things like a hawk but she grabbed something off the ground I missesd and I fished out a big spicy curly fry... got it all THANKfully!
During the game 2 really young kids were running around screaming and would swoop by and taunt her so I held her. She was watching them with ears up so I put her down (next to me would never let her go out to get creamed) and they started running up to her yelling and waving their hands right in her face trying to get her to play, then running off and around again. I wanted to see what she would do so let that go on since she wasn't distressed at all and finally she bounced toward one of the kids which made him scream and run off (he was playing) she decided that was kind of fun so in the end, she would run toward each screaming kid and as they would run away she would get up on her hind legs with her front paws straight up and out to the sides like a boogy man and run at them for several steps upright like that. She played with them for a long time. It was hilarious and I was SO proud of her to be able to handle that kind of situation and not be afraid or reactive in any way (not that I would expect that of her she never has been but that was an extreme test for her temperament).
Anyway point being I was braced this morning for a sick pup at some level but she got up, went a perfect potty, ate, then wanted to play! I don't let her play very hard after eating so I put her in her wire crate next to me that I stick out the open window a bit so she is laying here comfortably watching her neighborhood. She has burped a little but usually does after eating I wish I knew if that brings up acid and makes her feel bad at all. I don't see sign of it but those 8 years when I couldn't eat and stomach was so miserable some (inconsiderate!!) people would say "well you don't look sick!" when I felt heck and like I couldn't take anymore. So I am always questioning, is she tired today or is she quieter because her stomach is killing her....ugh.
But I'm thrilled she is feeling so good after all that last night but why that didn't bother her stomach and the nosework night did I don't know. Other than, nosework night, she was over the top beside herself to be there, and the ball game she is calmer at since there are no treats and working involved.
