I would also suggest [when your dog has settled a bit] taking her to a smaller pet store [Petco and Petsmart might be a bit overstimulating, especially during the holiday season] and showing her several different toys. She may enjoying browsing the aisles with you and may even pick out her own toy that appeals to her. We pull things off the rack for our girl to inspect; when she tries to take it from us or looks excited, we tend to get it because we want her to play.
There is also a toy that may bring your dog some comfort – I think it was designed for weaning puppies, dogs with separation anxiety or mourning pets, but it is a plush toy with a warming pack and a “beating heart” powered by a battery. There is a popular brand available at online retailers and Amazon called SnugglePuppy from Snuggle Pet Products. It is kind of expensive [you may be able to find another brand/model for less] for an experiment, but it may comfort her and help her transition her to her new environment and to liking toys/playing.
I would also recommend wrapping a plush toy in an old tshirt or stuffing it inside a sock that has your scent on it – you’re her pack/people now and she wants to smell like you so she won’t have to be alone again. [Our girl likes to jump in our dirty laundry and thrash under our bedcovers after her bath, probably thinking we won’t recognize her. She also takes off her Doggles whenever my fiance reenters the car]. Making the toy smell like you by putting it in the dirty clothes hamper will help reinforce that this toy belongs in the household, toys are fun and playing with you is a nice thing to do. Some non-plush toys can also have food smeared on them or treats stuffed inside to help get entice her to interact with them.
Playing is a great way to bond with your dog and give her a chance to exercise and feel comfortable inside in her new surroundings. Keep trying to teach her to play – no dog is too old to learn to have fun.
The most important thing to remember is to go slow and have a really positive attitude when dealing with toys – even if your dog’s behavior is upsetting – don’t get upset! Dogs read our emotions and getting worried and stressed over her reactions might be causing more of an issue. If you feel like crying over her reactions, take a break, take her for a walk and then just try to cuddle with her and her toy quietly. Rub her and pet her with the toy if she doesn’t act scared. If she wants it in her crate, let her have it there. Maybe she wants a toy to cuddle and protect and you could get her another toy for tossing, pulling and playing with you in the living room.
