Where to buy
With the G7 LPS, I got them all in store, but with older LPS I mainly use Ebay. Usually when I want to search for a specific pet, I will include the pet number, for example '#213'after "Littlest Pet Shop".
TIP: Include the full "Littlest Pet Shop" instead of LPS since you are more likely to get the results you are looking for as just typing "LPS" will get you music (vinyl) records for most of the results.
Bulk buying them is definitely a good way to go, you are able to get more pets at a cheaper price but the downside is you can't choose which ones/get ones you don't really want alongside the ones you do.Auctions are definitely another good way to get LPS at a cheaper price too. There are sellers that will sell LPS toys at a pretty reasonable price, so its good to compare prices of similar pets and deciding what you are willing to pay for for a pet.
TLDR: In-store for G7 & Ebay for older generation LPS
Custom LPS
Lucky
"A custom lps I commissioned from keyborgkitty on DA/toyhouse a while back. I still adore the little fish plushie they are holding! They overall did such an excellent job with this custom"
Generation 1
Chihuahua #385, Butterfly #397 and Shitzu #398
"The Shitzu is probably my favourite out of the three (I always thought it was a yorkshire terrier), though the other two are cute too like the butterfly and its glitterly eye patterns. However, I personally feel like the mold used for this chihuahua pet does not hold a light to the first. It may be fluffier but I feel it has less of that whimiscal charm."
Kitten #323 and Mouse #324 (Pet Pairs)
"What a cute set! The pairing of cat and mouse. The kitten LPS is my first flocked pet and still has quite a lot of flocking still on it after all this time. The little cheese chair the mouse comes with is so cute too, what's a mouse without some cheese. On another note, these two look so much like Tom & Jerry, so I think that's what I'll name them."
German Shepherd #127 and Snail #128 (Pet Pairs)
" Definitely one of my most favourite Pet Pairs set. The little raincoat and umbrella for the german shepherd is so cute! (The rain hat feels like it would be made out of the same material as an actual raincoat) Plus the designs and colour of both pets are so cute, they really complete each other."
Ferret #33
"Probably my most favourite LPS in the collection, just a little guy, has somewhat realistic proportions compared to later ferret molds. They will be the mascot for this page I think."
Jack Russel #109 (Seaside Celebration 3-Pack Scenery)
"Just look at him. This meme above reminded me so much of this particular LPS, the resemblance is uncanny"
"Turns out that this LPS might be fake! I never really noticed but this little guy has a white neck peg & no magnet on his foot! Also comparing him to the actual Jack Russel #109, this one's head is also wider and the face markings are less noticeable and has a squishier head to boot."
"Plus the glossier body, should have been a dead giveaway. But I don't know, he could just be a variant of some sort. I honestly didn't expect to run into fakes of earlier generation molds except for any popular ones. Genuinely I'm not upset though, just really interesting. I still really love this little guy."
Duck #108, Jack Russel #109, Kitten #110 (Seaside Celebration 3-Pack Scenery)
"This is overall such a cute set! I love beach-themed stuff in general. I'll include a picture of the whole set with the accessories at some point." Generation 2
Pig #475, Cow #476 and Lamb #477 (Pet-Lovin' Zoo 3-pack)
"Some pets from my childhood that I bought secondhand. They are all so cute, especially the lamb. I don't have all the accessories/parts of the original playset but I'm pretty happy to get all 3 pets."
Chow Chow #662 (Purse Pets On-The-Go)
"Probably one of my favourite pets in the collection atm, very cute!"
Generation 3
Bulldog #1765 (Multi Pack: 20-pack)
Corgi #1767 (Multi Pack: 20-pack)
"Love this corgi mold and the colours too!"
Lhasa Apso #2130 and German Shepherd #2137 (Multi Pack: Collector's 10-pack)
"These two are pretty cute especially the german shepherd. I definitely love the newer molds for the german shepherd more but the earlier ones are cute too."
One thing I have noticed with the newer G7 pet molds are the more squishier heads, some of the older pets I have somewhat squishy heads but G7's are just so squishy and the eye screening isn't the best either (the eye whites in particular don't show as well).
