Hi, I’ve got a four-year-old Jack Russell who has always gone up and down the stairs without any trouble; she's completely used to it. However, for about a week now, while she's still fine going up, she just stands at the top of the stairs whining until we come to help her down. We thought she might have had a fall and was scared of descending, but we’ve now noticed that she only seems afraid of the first and the last steps. Once we help her off the top step, she goes down the rest with no issues until she reaches the very bottom, where she stops again, starts whining and waits for us. If we don’t come to help, she eventually jumps from the second-to-last step to avoid the last one. I really don’t understand what could be bothering her.
Thanks in advance for your help! :)
