I feel awful saying this but… Old English Sheepdog.
My first was a dream and a typical Sheepie- huge, goofy, affectionate.
I love my current one but she’s very difficult. Extreme anxiety (and now medicated for it- it’s not really helping), very VERY territorial and constantly resource guards. We’ve spent a fortune on training and are experienced dog owners but I think she sadly has some form of personality disorder (we had a dog behaviour specialist in).
I know that sounds bizarre but I’ve never seen a dog like her. We’re now on our fifth groomer because the other four just couldn’t cope. Obviously, it’s a breed that needs a lot of grooming and we do a lot at home but for bigger jobs we’ve been having to sedate her to bring her to the groomers which we hate and is very upsetting. She gets very agitated if her coat is anything over a few inches long so we’re constantly having to shave her down and, whether at home or at the groomers, she hates it.
She’s gorgeous and great fun and we adore her but she’s 6st of muscle and angst. She is so strong that when she’s unhappy about something, she uses her size. She’s very dominant over smaller dogs- including her (non-OES) sister so we have to keep a very close eye (they adore each other but play can very quickly turn to dominance).
She breaks my heart sometimes when she looks at me because you can see by her eyes that she’s stressed and doesn’t understand what’s happening and it’s impossible to calm her down. she just doesn’t seem to be able to self-regulate at all.
She has many, many good points. She’s affectionate and funny and is well trained so can do plenty of tricks. Her recall is excellent but when she’s gets wound-up, everything goes out the window. She’s very clever and knows a huge amount of words so is always one step ahead of us. She’s also quite wary of cats (we have several) so it’s funny to see her slink back if a kitten wanders into the kitchen and then she very tentatively approaches with kisses. Two minutes later the kitten will have basically had a bath.
And, obviously, she’s gorgeous. When we’re out and about she attracts a lot of attention because of her size and fluffiness. She’s really good with kids- especially boisterous ones where she seems to move into Nanny mode and herds them around the place.
I love her, I just wish she would realise that if she relaxes a little, she’d make life much easier for herself.
