In 2023 (from June, when the written reason was first requested), 27.9% Partial period of the private individuals who explained in their own words why they were looking for a new home for their animal mentioned housing: 14.4% Partial period a home where pets are not allowed and 21.8% Partial period moving house. Among dogs, 29.2% Partial period; among cats, 22.8% Partial period.
From the platform list, 5.0% chose “pets not allowed at home” and 17.7% a change of address. The figures differ because only one option can be chosen from the list, whereas a single text can mention several topics.
It is the reason stated by the publisher: it does not measure how many people give up adopting because of housing or how many animals are abandoned because of it.

Read the full analysis
In 2023 (from 14 June 2023), 5,430 Partial period people sent 10,107 Partial period adoption requests. A request shows interest in a specific animal. It is not an adoption and does not allow us to calculate what share of requests ends in adoption.
31.1% Partial period of requests for dogs and 15.0% Partial period of requests for cats came from people in another province. By age, 27.5% Partial period of the people sending requests were aged sixteen to twenty-four and 24.4% Partial period twenty-five to thirty-four. According to their profile, 61.8% Partial period were women and 33.3% Partial period were men.
In their first three months, 64.3% Partial period of listed dogs and 64.7% Partial period of listed cats received no request through Miwuki. Organisations also receive interest through other channels, so this does not mean that nobody was interested.
What are people who want to adopt looking for?
- 41.5%live in a large home with a balcony, patio or terrace
- 41.7%already have another dog, a cat or another pet
- 26.1%have young children at home
- 17.7%are about to have their first dog

Among those who filled in the “Perfect pet” form in 2023 to adopt a dog, 41.5% lived in a large home with a balcony, patio or terrace and 13.3% in a small one without any of them. 41.7% already had another dog, a cat or another pet at home, 26.1% had young children and 9.5% had moved house in the last two years. For 17.7% it would be their first dog, and 62.9% said the animal would be alone for less than four hours a day.
71.6% ticked that they were looking for a small dog, 52.8% a medium-sized one and 22.1% a large one (several sizes can be ticked). 30.6% of those living in a large home with a balcony, patio or terrace were looking for a large one, compared with 11.8% of those living in a small one without them.
Only people who fill in the form answer it, so it does not represent everyone who adopts.

Outcomes
How many adoptions and returns were recorded, how long animals take to find a family and which profiles find it hardest. We only count what is recorded on Miwuki.
How many adoptions and returns were recorded?
- 6,650recorded adoptions
- 6,464different cases adopted
- 57.5%of 2023 cases, adopted at the cut-off date
- 106 Partial periodrecorded returns
Read the full analysis
In 2023, 6,650 adoptions of animals listed in Spain were recorded, corresponding to 6,464 distinct cases. These are the adoptions that publishers record on Miwuki; some adoptions may not be recorded.
Of the cases listed in 2023, 57.5% were marked as adopted on the cut-off date. These cases have had several years to find a family, so the percentage is not compared with other years.
In 2023, 106 Partial period returns were recorded from June, when they started being recorded regularly. This is not a return rate.
How long does it take to find a home?
- 52days to adoption: hard-to-place dogs
- 16days to adoption: puppies
- 49median days until an adult dog is adopted
- 79.7% Partial periodof senior dogs got no requests within 90 days
Read the full analysis
An adoption platform sees a part of the journey that other studies do not: how long each animal takes to find a family and how many attract no interest.
- The wait. Among shelter dogs listed in 2023 and adopted within 180 days, half of the puppies found a family in under 16 days and half of the adults in under 49; half of the hard-to-place dogs, in under 52.
- The invisible ones. 64.3% Partial period of dogs and 64.7% Partial period of cats listed received no request through Miwuki in their first 90 days; among senior dogs, 79.7% Partial period.

Among dogs listed by shelters in 2023, 88.6% of puppies had a recorded adoption 180 days after listing, compared with 44.4% of adults and 40.8% of seniors. Among cats, 74.7% of kittens compared with 38.4% of adults.
By age in years, 44.4% of dogs aged three to five and 42.2% of those aged nine or older were adopted within 180 days. Among those adopted within that period, half of the dogs were adopted in under 23 days (puppies: 16; adults: 49).
With the “hard to place” flag, 28.9% of dogs were adopted within 180 days, compared with 70.7% of the rest. With the PPP flag, 45.4%, compared with 68.8%. With leishmaniasis, 27.3%, compared with 68.1%.
Among dogs that had to be adopted together with another animal, 54.2% Small base; among those described as independent, 52.1%; and among those that get on with cats, 76.3%. Among cats, independent ones: 37.8%, compared with 62.2% of the rest.
In their first month, 13.7% Partial period of dogs with the “hard to place” flag received at least one request, compared with 32.3% Partial period of the rest.
These are associations, not causes: the profile alone does not explain the difference, and we only count the adoptions that shelters record on Miwuki. We compare profiles within 2023, not 2023 with other years, because how much shelters record changes over time.
Month by month
To compare months of different lengths, we show the daily average of each month.
- Summer (July and August): listed cases, 12.2% more per day than the rest of the year; recorded adoptions, 2.4% fewer per day than the rest of the year.
- Christmas (from 15 December 2023 to the following 6 January): listed cases, 19.8% fewer per day than in the previous three weeks; recorded adoptions, 9.2% more per day than in the previous three weeks.

Recommendations
- For families: give adults, seniors and animals flagged as hard to place a chance. Their temperament is already known and they are looking for a home too.
- For publishers: complete the profile and record adoptions and returns on Miwuki, including the reason. A complete profile is good practice; this report does not measure its effect.
- For Miwuki: document every change in the way data are recorded and keep this report's definitions so that years can be compared.

Miwuki Report on Pet Adoption in Spain · 2023 data · produced in 2026 with data as of 22 October 2026 · publication date: 24 October 2026.
It reconstructs what happened on Miwuki in Spain in 2023 with the report's current definitions and the data available at the cut-off date. It only includes what the platform recorded that year: when a data item did not exist yet, we say so.
What data exist for 2023 and what changed
New platform in June 2023. Since then:
- private individuals explain in writing why they are looking for a new home for their animal;
- breed is mandatory in the profile, which also records the health record book;
- adoption requests are recorded with their date, from 14 June 2023;
- dog size is taken from the breed;
- returns are recorded regularly.
This is why, in 2023, these data only cover the second half of the year.
What can we not conclude yet?
These data describe what happens on Miwuki, but they do not answer everything.
- How many animals are abandoned in Spain. Listing a case on Miwuki is not the same as an abandonment, and many organisations and families do not use the platform.
- Why the figures change. Fewer cases or fewer requests may be due to many factors, such as how many organisations use Miwuki or changes to the platform itself. We describe what happens, not its causes.
- What share of requests ends in an adoption. Requests and adoptions are counted separately and do not form a funnel.
- Why some profiles are adopted sooner than others. We show differences by age, size or the hard-to-place flag, but not their causes: photos, description, the organisation or the area also play a part.
- Whether COVID-19 increased adoptions. This is a hypothesis we are studying with controls; for now it is not a conclusion.
- Who adopts. Most recorded adoptions do not include data about the adopter.
- Whether private owners' animals find a home sooner or later than shelter animals. Most private owners do not record their animal's adoption on Miwuki, so their figure is a minimum.
- Where there is more abandonment. The breakdown by province reflects where Miwuki is used, not the incidence of abandonment, and the origin stated by shelters describes their cases, not the whole of Spain.
- The size of dogs compared with years before June 2023, because the way it is recorded changed.

2023 data · report produced in 2026
- 11,090 animal cases listed in Spain. 9.7% fewer than in 2022.
- 31.4% of the cases were cats. 5.1 percentage points lower than in 2022.
- 10,107 partial period adoption requests. Sent by 5,430 partial period people; a request is not an adoption.
- 6,650 adoptions recorded on the platform. 12.3% fewer than in 2022.
- 28.9% of hard-to-place dogs listed by shelters were adopted within 180 days. Compared with 70.7% of the rest (association, not causation).
Giving older and hard-to-place animals a chance makes a difference too.
