Poor Ollie :( Sounds like he sure had a rough go of it at the new groomer. I am very glad to see that you are going to have a vet check him over...that is definitely the first step just to be on the safe side.
Should that come out all clear, the next step is rebuilding Ollie's confidence. I would suggest short walks around your garden/yard with plenty of yummy safe treats, like small bits of boiled chicken breast (no skin, no bones, no seasonings) and with a cheery voice, good boy Ollie, that's a good boy and when he's happy, treat him. Then move to the end of the drive way, then a little way down the street, all doing the same routine. Take it very slowly with Ollie...going too fast will back fire on you. Do this over a period of a week at minimum. If he starts to get uncomfortable, go back to where he is calm again.
As time goes on, you can travel further and further. Do NOT tell him its ok in a soothing voice when he is nervous. This will just reinforce the negative behavior. Just ignore it and go back...on your terms though, not on his.
Since he's a younger dog, it will take some time but I think Ollie will do just fine and again, I can't stress taking this slowly enough. :)
I would also call the groomer and see how he behaved there. They may lie...they may tell you he was nervous in the cage but do ask about his behavior. I would also consider a mobile groomer if you can find one, for now..until Ollie becomes Ollie again.
Do pop in and let me know how its going with him and if you have further questions, please feel free to use the reply box or click the reply tab to reply to me.
Thanks so much and good luck with your boy!!!
Thats re assuring to hear, thnaks for your reply.
The other dog Oscar has always been nerous in the car but great on walks - do you think its possible Ollie is now mimicking his car behaviour? by panting and shaking and being nervous? We used to live seperatley but now we live together they are best buddies now and just wondered if he could have influensed him ?
Yes, it is possible. I rescued a bulldog that "taught" my mastiff to be thunderphobic so yes, it is possible, but considering you had the grooming situation before this started, its hard to tell.
Since Oscar (love the name) also has some behaviour issues, see if you can find a friend that can work with Oscar while you are working with Ollie doing the same thing.
As far as the car issues go..you can do the same thing. Do this one at a time...don't work them together. Bring one to the car on lead, get in the car, get out, in and out in and out...several times for several days. Next in the car with a treat like a kong toy stuffed with peanut butter. Do not start the car yet. The next week, do the same and start the car...don't move the car. The next week, move the car down the driveway. You see the routine here :) The biggest thing is to go slow and not make the car a stressful place. :)
I hope this has helped you further :)
Brilliant thanks again. Its really stressful when you dont know whats wrong but all we can do is try. I do believe that building his confidence is crutial aswell. Thanks so much.
