Advice on taking my shy dog to daycare
***Update*** Thank you so much everyone for your insight and advice. I've decided I will call around to independently owned daycares in the area and see if they groups for very small dogs, and how many dogs are in those groups. If I don't find a right fit I'm going to abandon the idea. ***
I'm looking for advice. I have a 4 year old mini doxie, Lana, who we adopted when she was 2. In her previous home she lived with several dogs...I also owned another dog when I adopted her but she passed away 3 months ago. Since my dog passed I feel bad that she has no doggie companion but I'm not yet ready to adopt another. She is overall a pretty reserved dog and it takes her time to warm up to new people and dogs. We've worked to socialize her with humans and she is now much more confident when it comes to human interaction. However we're having issues finding the right environment to introduce her to more dogs.
We live in an apartment and have had some successful on-leash meetings, though I know on-leash is not the recommended way to introduce dogs. If the other dog is too overbearing or jumpy she goes into defense mode and is then afraid of them. She has never attacked another dog or person however. Dog parks are a no go for me because there's too many variables with other dogs. We have some friends with dogs, but it's really hard for us to find the time to get together.
The other option is taking to doggie daycare, but I'm afraid that she'll be way too overwhelmed and be traumatized by it or become defensive with other dogs. In a perfect world we would take her 1-2 days a week so she gets time with other doggies.
People who have experience with a doggy daycare - is it a terrible idea to take her? I don't want to risk her safety or the safety of other dogs. Is there other options I haven't thought of for socializing her? Should I be taking more steps before I even attempt a day care?
