Unnecessary panicking: an essential part of the first year of owning a dog. We adopted our boy Buddy almost a year ago and I swear that almost every tiny blip felt like a complete failure. You will relax a bit more the longer Senner is with you, and some things that feel like failure at the minute, in six month’s time, you will learn to accept are things that you can’t (and probably don’t need to) change. I am by no means an experienced owner, but have eventually realised that when we adopted Buddy, we were put through a reasonably rigorous vetting process and were deemed to be competent to have a dog placed with us. It will be similar for you if you’ve adopted. Just keep doing what you’re doing and your care, love and attention will be rewarded.
And in addition, this site is brilliant for helping you to put things in perspective! I’ve only recently joined Greytalk but have read lots of threads over the past year, and these chats really help you work out what you need to be worried about (about 5% of what your greyhound does) vs. greyhound peculiarities (everything else, and then a bit more when you least expect it)
